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

    Recommendations for Mitigation

    Affected users are advised to apply the vendor’s patch, updating to versions 2.14.20, 3.2.0-rc2, 3.1.8 or 3.0.19. In the interim, a web application firewall (WAF) or an intrusion detection system (IDS) can be used to mitigate the risk of exploit.

    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.

  • CVE-2025-59147: Suricata Detection Bypass Vulnerability in Versions 7.0.11, 8.0.0 and Below

    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: 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.

    Vulnerability Summary

    CVE ID: CVE-2025-56301
    Severity: High (CVSS: 7.5)
    Attack Vector: Local
    Privileges Required: Low
    User Interaction: None
    Impact: System compromise or data leakage

    Affected Products

    Product | Affected Versions

    Chipsalliance Rocket-Chip | Versions prior to commit f517abbf41abb65cea37421d3559f9739efd00a9 (2025-01-29)

    How the Exploit Works

    The vulnerability arises from a flawed interaction between exception handling and exception return (MRET) mechanisms in the Control and Status Register (CSR) logic. When an MRET instruction is executed in machine mode without being in an exception state, an Instruction Access Fault may be triggered. This results in both the exception handling logic and the exception return logic activating simultaneously, leading to conflicting updates to the control and status registers. Consequently, this flaw can be exploited by an attacker to corrupt exception handling and privilege state transitions.

    Conceptual Example Code

    The following pseudocode demonstrates how the vulnerability could be exploited:

    // Enter machine mode without being in an exception state
    enterMachineMode();
    // Execute MRET instruction
    executeMRET();
    // The above triggers an Instruction Access Fault, activating both
    // the exception handling logic and the exception return logic simultaneously

    The above steps result in conflicting updates to the control and status registers, thereby corrupting exception handling and privilege state transitions. An attacker could potentially utilize this flaw to compromise the system or leak data.

    Mitigation

    Users are advised to apply the vendor patch immediately once available. In the meantime, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation.
