CVE-2024-55549 is a high-severity vulnerability in xmlsoft's libxslt, specifically in the function xsltGetInheritedNsList. This vulnerability allows a use-after-free condition due to the improper handling of result prefixes. The CVSS score for this vulnerability is 7.8, indicating a serious risk that organizations must address promptly.
The urgency for defenders is critical; organizations should prioritize patching immediately. If not addressed, this vulnerability could be exploited by attackers to cause significant damage.
As of now, there is no public exploit available, but the nature of this vulnerability suggests that it could be high-risk in real-world deployments.
Organizations relying on libxslt must be aware of this vulnerability and take appropriate measures to mitigate the risks associated with it.
Vulnerability Details
This vulnerability allows a use-after-free issue related to the exclusion of result prefixes. The affected version is any prior to 1.1.43. It has been categorized under CWE-416.
The CVSS score is 7.8, which signifies a high severity. This means that the vulnerability has a local attack vector, high complexity, and requires no privileges or user interaction.
Technical Analysis
The root cause of this vulnerability is a failure to properly manage memory, leading to a use-after-free condition that can be exploited under certain conditions. The attack vector is local, meaning that an attacker must have access to the system to exploit this vulnerability.
The attack complexity is high, as it requires specific conditions to be met. Additionally, the attacker needs no privileges and does not require user interaction. The vulnerability impacts the confidentiality, integrity, and availability of the system significantly.
Risk & Impact Analysis
Risk to organizations includes potential system crashes or unauthorized access to sensitive information. The blast radius can be significant, especially in environments where libxslt is utilized extensively.
Given the CVSS score and the current absence of known exploits, organizations should assess the urgency of their patching cycles. It is essential for security teams to prioritize remediation efforts to mitigate this vulnerability.
