Privileges Required: None
User Interaction: None
Impact: Denial of service, potential system compromise, or data leakage

Affected Products

Product | Affected Versions

Argo CD | 1.2.0 through 1.8.7, 2.0.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.2.0-rc1, 3.1.7 and 3.0.18

How the Exploit Works

The vulnerability stems from a flaw in Argo CD’s handling of API requests. With the default configuration, Argo CD’s /api/webhook endpoint will crash the entire argocd-server process when it receives a Gogs push event whose JSON field commits[].repo is not set or is null. This can be exploited by an attacker to send a malicious API request that crashes the API server and causes a denial of service.

Conceptual Example Code

Below is a conceptual example of a malicious HTTP POST request exploiting the vulnerability:

POST /api/webhook HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"commits": [
{
"repo": null
}
]
}

Mitigation Measures

To mitigate this vulnerability, users are advised to apply the vendor patch in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19. In the interim, use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.

Below is a conceptual example of a malicious HTTP request exploiting the vulnerability:

POST /api/webhook HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"repository": {
"links": {
"clone": "malformed_data"
}
}
}

Recommendations for Mitigation

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Suricata | 8.0.0

How the Exploit Works

The vulnerability stems from Suricata’s handling of the tls.subjectaltname keyword. A segmentation fault can occur when the decoded subjectaltname contains a NULL byte. An attacker can exploit this vulnerability remotely, without user interaction, by sending specially crafted network packets that trigger the segmentation fault, potentially leading to system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual example of a malicious network packet that an attacker might use to exploit this vulnerability.

POST /suricata/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/tls
{ "subjectaltname": "malicious\x00payload" }

In this example, the malicious payload contains a NULL byte (\x00), triggering the segmentation fault in Suricata 8.0.0.

Mitigation Guidance

Organizations are urged to apply the vendor patch by upgrading to Suricata 8.0.1 where this issue has been fixed. If upgrading isn’t immediately feasible, as a temporary mitigation, disable rules using the tls.subjectaltname keyword or employ a Web Application Firewall (WAF) or IDS.

Attack Vector: Network
Privileges Required: None
User Interaction: Not required
Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

Suricata | 8.0.0 and below

How the Exploit Works

The vulnerability exists due to incorrect handling of the “entropy” keyword when it is not anchored to a “sticky” buffer in Suricata. This incorrect handling can lead to a segmentation fault, causing the Suricata process to crash. An attacker can exploit this vulnerability by sending specially crafted network packets that trigger the incorrect behavior, leading to potential system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of a network packet that could potentially exploit this vulnerability. This is not a working exploit, but an example to illustrate the nature of the vulnerability:

POST /suricata/entropy HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
entropy=malicious_unanchored_value

Mitigation Guidance

Users are advised to update to Suricata version 8.0.1 or later, which contains a patch for this issue. If updating is not immediately possible, users can disable rules using the entropy keyword, or validate that they are anchored to a sticky buffer as a temporary workaround. Additionally, deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation.

Overview

This report discusses a significant cybersecurity vulnerability, CVE-2025-59147, affecting Suricata, a widely-used network intrusion detection system (IDS), intrusion prevention system (IPS), and network security monitoring engine. This vulnerability could potentially lead to system compromise or data leakage, posing a severe threat to any business or organization using the affected versions of Suricata.

Vulnerability Summary

CVE ID: CVE-2025-59147
Severity: High (CVSS: 7.5)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise, data leakage, and potential for detection and logging bypass.

Affected Products

Product | Affected Versions

Suricata | 7.0.11 and below
Suricata | 8.0.0

How the Exploit Works

The exploit operates by sending multiple SYN packets with varying sequence numbers within the same flow tuple. Suricata’s detection mechanism fails to properly recognize this as a single TCP session, leading to potential bypass of detection and logging in IDS mode. In IPS mode, this can result in the flow being erroneously blocked.

Conceptual Example Code

While the specific exploit wouldn’t involve an HTTP request or shell command, the logic of the vulnerability can be conceptually illustrated with pseudocode:

FOR i = 1 to n DO
SEND_SYN_PACKET(sequence_number = i)
ENDFOR

This pseudocode represents the sending of multiple SYN packets with different sequence numbers. The Suricata system treats these as separate sessions, leading to the bypass vulnerability.

Workarounds and Mitigation

Users are advised to apply the vendor’s patches provided in versions 7.0.12 and 8.0.1. If that is not immediately feasible, deploying a web application firewall (WAF) or an IDS can serve as a temporary mitigation measure. However, for long-term security, users should aim to update their Suricata installations as soon as possible.

Impact: Account takeover, unauthorized system access, potential system compromise, and data leakage

Affected Products

Product | Affected Versions

Corezoid | 6.6.0

How the Exploit Works

The vulnerability resides in the OAuth2 implementation of Corezoid 6.6.0. Specifically, it involves an open redirect in the redirect_uri parameter. This open redirect allows an attacker to intercept authorization codes by redirecting the victim to a malicious site controlled by the attacker. Once the attacker has the authorization codes, they can gain unauthorized access to the victim’s account.

Conceptual Example Code

Consider the following conceptual HTTP request:

GET /authorize?response_type=code&client_id=CLIENT_ID&redirect_uri=https://malicious.example.com&state=STATE HTTP/1.1
Host: vulnerable.example.com

In this example, the attacker has manipulated the redirect_uri parameter to point to a site they control (malicious.example.com). When the victim clicks on this manipulated link, they are redirected to the attacker’s site, where the authorization code is intercepted.

Mitigation Guidance

Users of Corezoid 6.6.0 are advised to apply the vendor patch immediately to mitigate the vulnerability. If a patch is not immediately available, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. These systems can detect and block malicious activity related to this vulnerability.

Impact: Successful exploitation can lead to system compromise, data leakage, and denial of service via excessive CPU usage.

Affected Products

Product | Affected Versions

Finance.js | v4.1.0

How the Exploit Works

This exploit works by abusing the IRR function’s depth parameter in Finance.js v4.1.0. The improper handling of the recursion/iteration limit can be manipulated to cause excessive CPU usage. This overuse of resources can then lead to application stalls or crashes, effectively rendering the service unavailable, hence causing a Denial of Service (DoS). More worryingly, it could potentially lead to system compromise or data leakage.

Conceptual Example Code

A potential exploit might involve sending a manipulated payload with an excessively deep iteration request to the IRR function. This could look something like this conceptually:

POST /IRR/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "depth": 1000000000 }

In this example, an attacker could send an HTTP POST request with a payload containing an abnormally high value for the depth parameter, causing the server to consume excessive CPU resources trying to process it.

Mitigation Guidance

The primary mitigation strategy for this vulnerability is applying the vendor-provided patch. It is recommended to update Finance.js to the latest version where this vulnerability has been addressed. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help provide temporary mitigation against potential attacks exploiting this vulnerability.
