Cisco PIX Private Link 4.1.6 and earlier does not properly process certain commands in the configuration file, which reduces the effective key length of the DES key to 48 bits instead of 56 bits, which makes it easier for an attacker to find the proper key via a brute force attack.

Security readout for executives and security teams

Cisco PIX Private Link 4.1.6 and earlier could weaken DES keys because some configuration commands were processed incorrectly. The practical issue is reduced cryptographic strength: a key intended to provide 56-bit DES security may effectively provide 48 bits, making brute-force recovery easier. Exposure appears limited to environments still running Cisco PIX Private Link 4.1.6 or earlier. The provided affected-product metadata is incomplete, so teams should confirm against Cisco records and local asset inventory rather than assume broader Cisco PIX exposure. Handle as a legacy cryptography exposure. It is not supported by active-exploitation evidence in the bundle, but any remaining affected deployment should be prioritized for replacement or vendor-guided remediation because weakened encryption can undermine confidentiality. Mitigation focus: Check the Cisco advisory for vendor-approved fixes or configuration guidance.; Inventory Cisco PIX Private Link versions and prioritize 4.1.6 or earlier.; Retire or isolate affected legacy deployments where feasible..
