Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Symlink attack enables local authentication bypass in PAM module, directly facilitating privilege escalation to root.
NVD Description
pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, symlink attacks on pad directory and pad files enable authentication bypass and root file corruption. This vulnerability is fixed in 0.8.7.
