68th percentile - higher than 68% of all known CVEs

Summary

Cisco PIX Private Link version 4.1.6 and earlier improperly processes certain commands in the configuration file, reducing the effective key length of the DES key to 48 bits instead of 56 bits.

Risk Assessment

This increases the risk that an attacker could more easily find the proper key via a brute force attack, potentially compromising data.

Recommendation

It is recommended to upgrade to a newer version of the software that fixes the command processing in the configuration file.
