Title: SGI IRIX RPC.MountD Read-Mostly Mount Unspecified File Access Vulnerability
Severity: HIGH
Description:
SGI IRIX is susceptible to an unspecified file access vulnerability. This issue is due to a failure of the NFS server to properly enforce privileges on client computers.
This issue allows client computers to gain access beyond that which the administrator has allowed. In certain unspecified circumstances, NFS clients may gain inappropriate read-write access to files contained in read-mostly network shares.
This vulnerability may allow remote attackers to modify files hosted on affected servers. Attackers may modify or destroy potentially sensitive files. It may also be possible for attackers to modify or replace binaries on shared filesystems. This likely results in the attacker-supplied code being executed from multiple computers sharing the affected filesystem. Other attacks may also be possible.
SGI IRIX versions 6.5.25 through 6.5.27 are vulnerable. Previous versions may also be affected.
Affected Products:
- SGI IRIX 6.5.25
- SGI IRIX 6.5.26
- SGI IRIX 6.5.27
