Description:
Tomasz Grabowski has reported some vulnerabilities in Platform LSF, which can be exploited by malicious people to impersonate other users, gain escalated privileges, and potentially compromise a vulnerable system.
1) It is possible to communicate with LSF while impersonating another user due to an authentication error in the eauth component. The problem is that a UID specified in the "LSF_EAUTH_UID" environment variable may be used instead of a user's real UID when performing actions on a LSF cluster.
This reportedly makes it possible to submit and control jobs (some with administrative privileges) as another user within a LSF cluster.
2) A boundary error in the eauth component allows malicious users to gain escalated privileges or compromise a system within a LSF cluster when eauth runs in "-s" mode. This can be exploited to cause a buffer overflow by supplying an overly long input string to the "LSF_From_PC" parameter.
This allows execution of arbitrary code with administrative privileges.
Versions 4.x, 5.x, and 6.x are reportedly affected by the vulnerabilities.
