This vulnerability allows a buffer overflow in GNOME libsoup before 3.6.1, specifically in applications that perform conversion to UTF-8 in the function soup_header_parse_param_list_strict. Although there is no confirmed public exploit, there is a plausible way to trigger this vulnerability remotely via the soup_message_headers_get_content_type function. Applications relying on this functionality may be at risk of exploitation.
The CVSS score for this vulnerability is 6.5, classifying it as medium severity. Organizations utilizing the affected version of libsoup should be aware of this risk, as it can lead to potential unauthorized access and data compromise.
Risk to organizations includes potential data loss and system instability. Given the nature of the buffer overflow, it may be exploited under specific conditions, necessitating immediate attention to ensure systems remain secure.
Organizations should prioritize patching immediately to mitigate this risk and protect their systems from potential exploitation.
Vulnerability Details
The official CVE description states that GNOME libsoup before 3.6.1 allows a buffer overflow in applications that perform conversion to UTF-8 in soup_header_parse_param_list_strict. The vulnerability is categorized under CWE-787, indicating a buffer overflow issue.
The vulnerability has a CVSS 3.1 score of 6.5, indicating a medium severity level. Its attack vector is classified as NETWORK, with high attack complexity and no privileges required for exploitation. The potential impacts include low confidentiality, integrity, and availability.
Affected product: libsoup. Vendor: GNOME. The vulnerability was published on November 11, 2024, and its status has been modified. The CWE classification is available as CWE-787.
Technical Analysis
The root cause of this vulnerability stems from improper handling of input when converting to UTF-8. The attack vector is network-based, allowing an attacker to send specially crafted input to trigger the overflow. The attack complexity is high, indicating that successful exploitation would require significant effort on the part of the attacker.
No user interaction is required, and no privileges are necessary to exploit this vulnerability. The impacts on confidentiality, integrity, and availability are assessed as low, but the potential for data corruption or service disruption remains.
Risk & Impact Analysis
Organizations using the affected versions of libsoup should assess their exposure to this vulnerability, particularly if their applications handle untrusted input. The risk includes potential data loss, unauthorized access, and system instability. The blast radius for exploitation could be significant if widely deployed applications are vulnerable.
The urgency for remediation is classified as medium. Organizations should schedule remediation as part of their regular patch cycle, ensuring that systems are updated to version 3.6.1 or later to address this vulnerability effectively.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to vendor patch are affected, specifically those before 3.6.1. Organizations using libsoup should immediately upgrade to the latest version to remediate this vulnerability.
Mitigation & Remediation
Patching is the primary means of remediation. Organizations should upgrade to libsoup version 3.6.1 or later. If immediate patching is not feasible, consider implementing workarounds, such as input validation and sanitization to mitigate risks associated with this vulnerability. It is also advisable to conduct regular security audits and assessments, such as penetration testing to identify potential weaknesses.
Detection Guidance
Organizations should monitor logs for any anomalies associated with libsoup usage. Look for unexpected crashes or memory access violations that may indicate exploitation attempts. Additionally, implementing network signatures to detect suspicious traffic could help in early detection of potential exploitation.
