CVE-2024-10963Source published Source updated
A flaw was found in pam_access, where certain rules in its configuration file are mistakenly treated as hostnames. This vulnerability allows attackers to trick the system by pretending to be a trusted hostname, gaining unauthorized access. This issue poses a risk for systems that rely on this feature to control who can access certain services or terminals. This vulnerability in pam_access is rated with an Important severity because it directly impacts the integrity of access control mechanisms in secure environments.

- Mitigation guidance
- To reduce the risk, administrators should ensure that no DNS hostname matches local TTY or service names used in pam_access. Additionally, implement DNSSEC to prevent spoofing of DNS responses. For stronger protection, consider reconfiguring pam_access to only accept fully qualified domain names (FQDNs) in access.conf
