CVE-2024-58134

Mojolicious versions from 0.999922 through 9.40 for Perl uses a hard coded string, or the application's class name, as a HMAC session secret by default

Description

Mojolicious versions from 0.999922 through 9.40 for Perl uses a hard coded string, or the application's class name, as a HMAC session secret by default. These predictable default secrets can be exploited to forge session cookies. An attacker who knows or guesses the secret could compute valid HMAC signatures for the session cookie, allowing them to tamper with or hijack another user’s session.

Remediation

Workaround:

  • Ensure that your Mojolicious application uses a unique secret of at least 128 bit of cryptographically secure random data. For example, to generate a 256 bit secret, one could use the output generated by the "openssl rand -base64 32" command.
