CVE-2023-31130
4.1 · MEDIUMOverview
CVE-2023-31130 is a medium-severity vulnerability affecting c-ares_project c-ares. It was published on May 25, 2023 and has a CVSS 3.1 base score of 4.1 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 4.1, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1.
Remediation
Check the references section for vendor advisories and patches from c-ares_project. Update c-ares to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
