CVE-2022-25147 is a medium severity vulnerability classified as an integer overflow or wraparound in the apr_base64 functions of the Apache Portable Runtime Utility (APR-util). This vulnerability allows an attacker to write beyond the bounds of a buffer, which could lead to various security risks.
The CVSS score for this vulnerability is 6.5, indicating a medium severity level. This is significant as it suggests that while exploitation may require some specific conditions, the potential impact could still be detrimental to organizations, particularly those using affected versions of the software.
Risk to organizations includes unauthorized access and manipulation of data leading to integrity and availability issues. Organizations should prioritize patching immediately to mitigate these risks.
Currently, there are no known exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, the lack of public proof-of-concept (PoC) should not deter organizations from addressing the vulnerability promptly.
Organizations using Apache Portable Runtime Utility (APR-util) version 1.6.1 and prior should take immediate action to assess their systems and apply the necessary patches as they become available.
Vulnerability Details
The vulnerability allows an attacker to exploit integer overflow conditions, particularly in the apr_base64 functions, which are part of the Apache Portable Runtime Utility (APR-util).
The affected product is Apache Portable Runtime Utility (APR-util) version 1.6.1 and earlier, and it was published on January 31, 2023. The vulnerability is classified under CWE-190.
The CVSS 3.1 vector string for this vulnerability is: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L, which indicates that exploitation can occur over the network with low complexity and no privileges required.
Technical Analysis
The root cause of this vulnerability is an integer overflow condition that occurs in the apr_base64 functions. This oversight may allow attackers to manipulate data in a way that exceeds the intended limits of the buffer, leading to potential data corruption or crashes.
The attack vector is network-based, and the attack complexity is considered low, meaning that it may not require advanced skills to exploit. No user interaction is required, which increases the risk of exploitation.
The vulnerability has low confidentiality impact as it does not compromise data confidentiality. However, it has a low integrity impact, which means it could allow for unauthorized changes to data, and a low availability impact, which might lead to service disruptions.
Risk & Impact Analysis
Organizations should evaluate the risk posed by this vulnerability in the context of their specific deployment environments. The potential for unauthorized changes and service disruptions highlights the need for immediate remediation.
The urgency of addressing this vulnerability is underscored by its CVSS score of 6.5, indicating a medium severity level. Organizations should address in priority patch cycle to minimize risks.
