CVE-2026-47373

7.5

RRWO · Crypt::SaltedHash

The Crypt::SaltedHash Perl module is vulnerable to a timing discrepancy attack, potentially allowing attackers to determine sensitive hash information via observable response times.

Executive summary

A timing discrepancy vulnerability in Crypt::SaltedHash allows for potential unauthorized information disclosure via side-channel analysis.

Vulnerability

This vulnerability (CWE-208) involves an observable timing discrepancy during hash comparisons. It is an unauthenticated vulnerability accessible over the network, which may allow an attacker to infer information about hashes through side-channel timing analysis.

Business impact

The ability to perform timing-based attacks against cryptographic functions can lead to unauthorized information disclosure, weakening the security of password storage or token verification. With a CVSS score of 7.5 (High), this vulnerability represents a significant risk to systems relying on this module for secure authentication or data integrity.

Remediation

Immediate Action: Upgrade to Crypt::SaltedHash version 0.10 or later.

Proactive Monitoring: Monitor authentication systems for abnormal request latency patterns that could indicate a timing-based side-channel attack.

Compensating Controls: In environments where patching is delayed, ensure that the application logic does not expose granular timing information to external entities.

Exploitation status

Public Exploit Available: Unknown

Analyst recommendation

Given the sensitivity of cryptographic modules, upgrading to version 0.10 is essential to resolve the timing discrepancy. Organizations should ensure this update is integrated into their dependency management cycles immediately to maintain robust security posture.
