"The remote NewStart CGSL host, running version MAIN 7.02, has pam packages installed that are affected by multiple
vulnerabilities:

  - 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. (CVE-2024-10963)

  - A vulnerability was found in PAM. The secret information is stored in memory, where the attacker can
    trigger the victim program to execute by sending characters to its standard input (stdin). As this occurs,
    the attacker can train the branch predictor to execute an ROP chain speculatively. This flaw could result
    in leaked passwords, such as those found in /etc/shadow while performing authentications. (CVE-2024-10041)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
