Overview

This report addresses a significant vulnerability, CVE-2025-40779, found in the Kea DHCP server. If a DHCPv4 client sends a request containing specific options and Kea fails to find an appropriate subnet for the client, the `kea-dhcp4` process could abort, causing a system failure. This vulnerability affects multiple versions of Kea, and if exploited, could potentially lead to a system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-40779
Severity: High (7.5 CVSS Score)
Attack Vector: DHCPv4 Client Request
Privileges Required: None
User Interaction: None
Impact: System compromise, data leakage

Affected Products

Product | Affected Versions

Kea | 2.7.1 – 2.7.9
Kea | 3.0.0
Kea | 3.1.0

How the Exploit Works

The exploit works when a DHCPv4 client sends a request with specific options to the Kea server. If Kea fails to find an appropriate subnet for the client, the `kea-dhcp4` process aborts due to an assertion failure. This vulnerability only affects if the client request is unicast directly to Kea; broadcast messages are not impacted by this issue.

Conceptual Example Code

The vulnerability can be potentially exploited by sending a malformed DHCPv4 client request to the Kea server, as illustrated in the conceptual pseudo-code below:

DHCPv4_Request {
HOST: Kea_Server_IP
Specific_Options: Malicious_payload
Request_Type: Unicast
}

In this pseudo-code, a DHCPv4 request is sent to the Kea server with malicious payload placed within the specific options. This can trigger a failure in the `kea-dhcp4` process if Kea cannot find an appropriate subnet for the client.

Overview

A notable vulnerability has been identified in the Gestionnaire Libre de Parc Informatique (GLPI), specifically in versions 10.0.0 to before 10.0.19. This vulnerability, identified as CVE-2025-53105, allows a connected user without administration rights to change the rules execution order, potentially leading to system compromise or data leakage. The severity of this vulnerability underlines the importance of its immediate resolution amongst users of the affected GLPI versions.

Vulnerability Summary

CVE ID: CVE-2025-53105
Severity: High (7.5)
Attack Vector: Network
Privileges Required: Low
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

GLPI | 10.0.0 to before 10.0.19

How the Exploit Works

The exploit works by taking advantage of the weak user role management in the GLPI software. A user without administrative privileges can manipulate the order in which the rules execute. This could potentially lead to unexpected behavior of the software, data leakage, or even a full system compromise if the rules are configured to perform critical operations.

Conceptual Example Code

An example of how this vulnerability might be exploited is illustrated below. This is a conceptual example and may not represent an actual exploit.

POST /changeRuleOrder HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"ruleId": "1001",
"newPosition": "1"
}

In this example, the attacker sends a POST request to the ‘changeRuleOrder’ endpoint, attempting to reposition a rule identified by “ruleId” to a new position in the execution order. The successful execution of this request could result in the unauthorized modification of the GLPI software’s rules execution sequence.

Recommendation

Users are strongly advised to upgrade to version 10.0.19 or later where this vulnerability has been patched. In the interim, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation.

Attack Vector: Local
Privileges Required: Low
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Agiloft | Release 28

How the Exploit Works

The exploit takes advantage of several accounts in Agiloft Release 28 that have default credentials. An attacker with local access can escalate their privileges by cracking the known hash of at least one of these accounts. The credentials can be cracked offline, enabling the attacker to gain unauthorized access and cause potential damage or data leakage.

Conceptual Example Code

Although no actual code is provided, a possible attack scenario could be as follows:
1. The attacker obtains the known password hash from the local system.
2. The attacker cracks the hash offline to obtain the plaintext password.
3. The attacker uses the cracked password to log into the system with escalated privileges.

# Step 1: Obtain the known password hash
cat /etc/shadow | grep agiloft_account
# Step 2: Crack the hash offline
john --wordlist=password.lst hash.txt
# Step 3: Log into the system with escalated privileges
ssh agiloft_account@target-system

Please note that the above steps are a conceptual demonstration and may not reflect the exact steps an attacker would use to exploit this vulnerability.

Mitigation Guidance

Users are strongly advised to upgrade to Agiloft Release 30 to remedy this vulnerability. As a temporary mitigation, users could apply vendor patches or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS).

Attack Vector: Remote
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise and data leakage due to unapproved data access and remote information disclosure

Affected Products

Product | Affected Versions

[Product 1] | [Version 1.0 – 1.5]
[Product 2] | [Version 2.0 – 2.7]

How the Exploit Works

The vulnerability stems from a missing permission check in the handleBondStateChanged function of AdapterService.java. This allows for the possibility of unapproved data access. An attacker could potentially exploit this flaw by inducing a user to execute certain actions, leading to information disclosure.

Conceptual Example Code

This is a conceptual example of how the vulnerability might be exploited:

// Malicious code exploiting the vulnerability
public class Exploit {
public static void main(String[] args) {
AdapterService adapterService = new AdapterService();
// Trigger the handleBondStateChanged event
adapterService.triggerEvent("handleBondStateChanged", new EventData("malicious_data"));
}
}

This example shows how an attacker could exploit the vulnerability by triggering the ‘handleBondStateChanged’ event with malicious data.
To mitigate this vulnerability, vendors are encouraged to apply the appropriate patch or utilize a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary measure. However, these mitigations should not replace the need for a permanent fix, which should be applied as soon as it becomes available.

Overview

This report details a critical vulnerability, identified as CVE-2025-0081, that is present in the dng_lossless_decoder::HuffDecode function of dng_lossless_jpeg.cpp. The vulnerability can potentially cause a system crash due to uninitialized data, leading to a remote denial of service. It poses a substantial threat to the integrity and availability of the affected systems and requires immediate addressing to prevent any potential system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-0081
Severity: High (CVSS 7.5)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Remote Denial of Service leading to potential system compromise or data leakage

Affected Products

Product | Affected Versions

dng_lossless_jpeg.cpp | All versions prior to patch

How the Exploit Works

The exploit takes advantage of uninitialized data within the dng_lossless_decoder::HuffDecode function. An attacker can craft a specific payload that when processed by this function, can cause system instability or a crash. The crash occurs due to a lack of proper initialization, which can cause the system to read unallocated memory or perform an operation that the system memory is not prepared for, resulting in a crash and denial of service.

Conceptual Example Code

The exploit might be delivered through a malicious payload embedded in a network request. The following is a conceptual example:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/dng_lossless
{ "malicious_payload": "uninitialized_data_trigger" }

In this example, the “uninitialized_data_trigger” represents a payload that would trigger the uninitialized data vulnerability in the dng_lossless_decoder::HuffDecode function.
Please note that this is a conceptual representation, and real exploit code may be more complex and specific to the software and vulnerability in question.

Overview

The vulnerability identified as CVE-2025-57803 presents a significant risk to users of ImageMagick, a widely used open-source software for editing and manipulating digital images. The flaw can lead to potential system compromise or data leakage, affecting versions of ImageMagick prior to 6.9.13-28 and 7.1.2-2 for the 32-bit build.

Vulnerability Summary

CVE ID: CVE-2025-57803
Severity: High (7.5 CVSS score)
Attack Vector: Local
Privileges Required: None
User Interaction: No
Impact: System Compromise, Information Disclosure

Affected Products

Product | Affected Versions

ImageMagick | Prior to 6.9.13-28
ImageMagick | Prior to 7.1.2-2

How the Exploit Works

The exploit is based on a 32-bit integer overflow in ImageMagick’s BMP encoder’s scanline-stride computation. This overflow results in the collapse of bytes_per_line (stride) to a very small value. However, the per-row writer still emits 3 × width bytes for 24-bpp images. Consequently, the row base pointer advances using the overflowed stride. This leads to the first row immediately writing past its allocated heap memory and overwriting adjacent heap memory with attacker-controlled bytes. This sort of heap corruption is a common and potent attack vector in common auto-convert pipelines.

Conceptual Example Code

While actual exploit code isn’t available, an attacker might exploit the vulnerability by providing a specially crafted BMP image that triggers the integer overflow. The following pseudocode illustrates this concept:

Create BMP image with width that triggers integer overflow
Embed malicious payload in image data
Upload or submit image to ImageMagick processing pipeline

Upon successful exploitation, an attacker could potentially execute arbitrary code or cause information disclosure. Immediate patching or use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation measures. However, upgrading to a non-vulnerable version of ImageMagick is highly recommended.

Overview

The vulnerability CVE-2025-55298 is a significant cybersecurity issue that directly affects ImageMagick, a widely used open-source software for editing and manipulating digital images. The flaw lies in the lack of proper input sanitization in the InterpretImageFilename function, which can be exploited by attackers to overwrite arbitrary memory regions. The impact of this vulnerability is substantial as it puts systems at risk of compromise and potential data leakage.

Vulnerability Summary

CVE ID: CVE-2025-55298
Severity: High (CVSS: 7.5)
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

ImageMagick | Prior to 6.9.13-28
ImageMagick | Prior to 7.1.2-2

How the Exploit Works

The exploit works by taking advantage of the format string bug vulnerability in the InterpretImageFilename function in ImageMagick. An attacker can manipulate user input that is directly passed to the FormatLocaleString function without proper sanitization. By crafting a specific payload, an attacker can overwrite arbitrary memory regions, leading to a potential heap overflow or even remote code execution.

Conceptual Example Code

Assuming an attacker has the ability to influence the user input that is passed to the FormatLocaleString function in ImageMagick, the conceptual exploit might look something like this:

./convert 'fmtstr_payload.jpg' output.png

In this conceptual example, ‘fmtstr_payload.jpg’ is a maliciously crafted image file that takes advantage of the format string vulnerability. When ImageMagick tries to convert this image, it would execute the malicious payload contained within it, leading to potential system compromise.

Overview

User Interaction: Required
Impact: Possible system compromise and data leakage

Affected Products

Product | Affected Versions

SelectZero Data Observability Platform | Before 2025.5.2

How the Exploit Works

The exploit works by exploiting the improper sanitization of parameters within the SelectZero Data Observability Platform’s login page. Attackers can inject arbitrary text or limited HTML into these parameters, which can then be displayed on the login page. This manipulation could potentially lead to fraudulent messages or misleading information being shown, which could trick users into performing actions that compromise the system or reveal sensitive data.

Conceptual Example Code

The following is a conceptual example of a malicious HTTP POST request that could exploit this vulnerability:

POST /login HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=normalUser&password=<b>Security%20Update:%20Please%20send%20your%20password%20to%20admin@example.com%20for%20verification</b>&remember_me=true

In this example, the attacker injects HTML code into the “password” parameter that would appear as a security update message on the login page, potentially tricking users into sending their passwords via email.

Mitigation

To mitigate this vulnerability, users of the affected versions of the SelectZero Data Observability Platform should apply the vendor’s available patch as soon as possible. As a temporary mitigation, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and block attempts to exploit this vulnerability.

How the Exploit Works

The vulnerability stems from the lack of SPI Protected Range Registers (PRRs) in the mentioned versions of the RSUs. This omission allows attackers with low-level privileges and local access to manipulate the SPI flash memory in real-time. This could lead to unauthorized changes in system behavior or data leaks.

Conceptual Example Code

Here is a conceptual pseudo-code example illustrating how an attacker might exploit this vulnerability:

def exploit(target_system):
# Obtain low-level privileges on the target system
low_privileges = obtain_low_privileges(target_system)
if low_privileges:
# Access the SPI flash memory
spi_flash = access_spi_flash(target_system)
# Modify the SPI flash memory in real-time
spi_flash.modify("malicious_changes")
else:
print("Failed to obtain necessary privileges.")

This pseudo-code is for illustrative purposes only. In real-world scenarios, detailed knowledge of the system and the exploit would be necessary.
