Yahoo! Messenger < 184.108.40.2063 File Extension Spoofing
Medium Nessus Network Monitor Plugin ID 3700
SynopsisThe remote host may be tricked into running an executable file.
DescriptionThe remote host is running a version of Yahoo! Messenger that is reported vulnerable to a remote file extension spoofing flaw. Specifically, if a user sends a malformed download query that includes many '[email protected]' sequences, the displayed name of the file will obfuscate the true file type. An attacker can use this flaw to trick users into downloading files that they believe are not malicious. Successful exploitation might lead to the attacker executing arbitrary executables on the target system.
SolutionUpgrade to a version higher than 220.127.116.113.
