SAP Router Route Permission Table Password Timing Side Channel

IdentifiersCVE-2014-0984CWE-208

CVE-2014-0984 is an observable timing discrepancy in the passwordCheck function of SAP Router. Affected releases terminate Route Permission Table password validation when the first incorrect character is encountered. The resulting response-time variation reveals the length of a correct password prefix, permitting incremental recovery of the password through timing-guided brute-force guesses.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A remote attacker can recover a Route Permission Table entry password by measuring response-time differences across repeated password guesses. Compromise of such a password can enable unauthorized use of the associated route permission, undermining SAP Router access controls.

Mitigation

If you can’t patch tonight, do this now.

Use constant-time password-verification logic that processes the complete value before returning a result, without early termination on a mismatched character. Password-verification designs should compare fixed-length cryptographic password hashes rather than raw password strings and ensure failure paths have indistinguishable timing behavior.

Remediation

Patch, then assume compromise.

Upgrade SAP Router to a vendor-fixed version that eliminates the early-exit password comparison. Password validation should process all relevant characters regardless of where a mismatch occurs and return responses with non-distinguishable timing characteristics.
