Sun Solaris patchadd symlink attack
| solaris-patchadd-symlink (5789) |  Medium Risk |
Description:
Sun Solaris is vulnerable to a symbolic link attack, due to a vulnerability in patchadd. Patchadd is a patch management tool used to install patches on Solaris. When patchadd is executed, files are created in the /tmp directory with mode 0666, using predictable file names, which include the pid of patchadd. A local attacker can guess the pid of patchadd and create temporary files in the /tmp directory that are symbolically linked to system files. An attacker can use this vulnerability to gain elevated privileges, execute arbitrary commands on the system, or corrupt system files.
Platforms Affected:
