Published May 3, 2025CWE-338EPSS 0.57%

Overview

CVE-2024-58135 is a medium-severity vulnerability. It was published on May 3, 2025 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Mojolicious versions from 7.28 through 9.45 for Perl will generate weak HMAC session cookie secrets via "mojo generate app" by default.

When creating a default app skeleton with the "mojo generate app" tool, a weak secret is written to the application's configuration file using the insecure rand() function, and used for authenticating and protecting the integrity of the application's sessions. This may allow an attacker to brute force the application's session keys.

Release 9.46 fixes the issue by providing high quality randomness, even in absence of CryptX.

Users should be aware that the update does not replace previously generated weak secrets. A secret generated with the previous version MUST be replaced to ensure the updated version is using a strong secret.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
