AI Analysis
Technical Summary
This vulnerability in the ZTE ZXCLOUD iRAI client (version 7.2X) is due to improper handling of externally-controlled format strings, classified as CWE-134. Exploiting this issue can cause memory corruption resulting in a denial-of-service condition remotely. The CVSS 3.1 base score is 4.7, reflecting medium severity, with attack vector local, high attack complexity, low privileges required, and no impact on confidentiality or integrity, only availability.
Potential Impact
Successful exploitation leads to remote denial of service through memory corruption. There is no impact on confidentiality or integrity of data. The attack requires local access with low privileges and has high complexity, limiting the ease of exploitation. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
