CVE-2023-52168 is a high-severity vulnerability identified in the NtfsHandler.cpp NTFS handler of 7-Zip prior to version 24.01. This flaw allows attackers to exploit a heap-based buffer overflow, which could lead to memory corruption. The severity of this vulnerability, with a CVSS score of 8.4, highlights the potential for significant impact on affected systems.
Risk to organizations includes unauthorized access and potential control over the affected systems. The attack vector is local, meaning an attacker must have access to the vulnerable system. With low attack complexity and no required privileges or user interaction, the risk of exploitation is pronounced. Organizations should prioritize patching immediately.
As of now, this vulnerability is awaiting analysis, which means detailed exploitation information has not yet been confirmed. However, due to its nature and severity, immediate attention is warranted from security teams to mitigate potential risks.
Organizations should be vigilant, especially those utilizing 7-Zip for handling NTFS files, and must take steps to safeguard against this vulnerability to prevent exploitation.
Vulnerability Details
The NtfsHandler.cpp NTFS handler in 7-Zip before version 24.01 contains a heap-based buffer overflow that allows an attacker to overwrite two bytes at multiple offsets beyond the allocated buffer size. Specifically, this overflow occurs at buffer+512*i-2, for i=9, i=10, i=11, etc.
The CVSS score of 8.4 indicates a high severity level, with significant implications for confidentiality, integrity, and availability. Affected systems are those using 7-Zip before the patch, with a publication date of July 3, 2024.
Technical Analysis
The root cause of this vulnerability lies within the NTFS handler's code, where improper bounds checking leads to a buffer overflow. The attack vector is local, requiring the attacker to have access to the system running 7-Zip. Attack complexity is low, with no privileges required and no user interaction necessary.
The impacts of this vulnerability are severe, affecting confidentiality, integrity, and availability with a high impact score. Attackers may leverage this vulnerability to execute arbitrary code or manipulate the system, leading to unauthorized access.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-52168 is substantial, especially in environments where 7-Zip is implemented for file compression and extraction. Given the ability to overwrite memory, the potential blast radius could affect critical systems where sensitive data is processed.
Organizations should recognize that the urgency for remediation is high, given the CVSS score and the implications for data security. Security teams must prioritize this vulnerability in their patch management processes to mitigate the risks.
