[原文]The command line interface (CLI) in Cisco Unified CallManager (CUCM) 5.0(1) through 5.0(3a) allows local users to overwrite arbitrary files by redirecting a command's output to a file or folder, aka bug CSCse31704.
Unified CallManager contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered by an unspecified flaw in the CLI that may allow a logged-in administrator to write arbitrary files as the root user of the base operating system. This flaw may lead to a loss of integrity.
Upgrade to version 5.0(4) or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
