AI Analysis
Technical Summary
CVE-2024-14042 affects Open5GS versions up to 2.7.1 in the functions hss_ogs_diam_s6a_air_cb and hss_ogs_diam_s6a_ulr_cb within src/hss/hss-s6a-path.c. The vulnerability is a stack-based buffer overflow caused by manipulation of the argument os.len. This flaw can be exploited remotely. A patch identified by commit e89aa79efe629ae90f59dcdf8847c117d9a7da86 is available in version 2.7.2 to address this issue.
Potential Impact
Successful exploitation can lead to a stack-based buffer overflow, potentially causing denial of service or limited information disclosure. The CVSS 3.1 base score is 6.3 (medium severity) with network attack vector, low attack complexity, requiring low privileges, no user interaction, and impacts on confidentiality, integrity, and availability. Exploit code is publicly available, increasing the risk of exploitation.
Mitigation Recommendations
Upgrade Open5GS to version 2.7.2 or later, which includes the official patch (commit e89aa79efe629ae90f59dcdf8847c117d9a7da86) that fixes the stack-based buffer overflow vulnerability. No other mitigations are specified by the vendor advisory.
