Technical Analysis
IBM Security Verify Access versions 10.0 to 10.0.9.2 and IBM Verify Identity Access versions 11.0 to 11.0.3 contain an argument injection vulnerability (CWE-88) that could allow a remote attacker with authentication privileges to execute unauthorized commands. This occurs due to improper neutralization of argument delimiters in command processing, potentially leading to elevated privileges or unauthorized actions within the affected software.
Potential Impact
Successful exploitation of this vulnerability could result in complete compromise of the affected system's confidentiality, integrity, and availability, as indicated by the CVSS vector (C:H/I:H/A:H). The attacker must be authenticated but can perform unauthorized actions remotely, which may lead to significant operational and security impacts.
Mitigation Recommendations
No explicit patch or remediation information is provided in the available data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is confirmed, restrict access to affected systems to trusted users only and monitor for suspicious activity related to command injection attempts.
