CVE-2026-118991

CallBackery versions before 0.62.0 for Perl encrypt configuration backups with the padded password as the AES key

Published Oct 30, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
CallBackery versions before 0.62.0 for Perl encrypt configuration backups with the padded password as the AES key.

getCrypt() pads the backup password with "x" characters and cuts it to 32 bytes to form the AES key, with no salt and no key derivation. The first block of a backup holds a 16 hex digit length field, so decrypting one block confirms a password guess at raw AES speed.

An attacker who obtains a backup can recover its password by fast offline guessing, and with it every credential the backup holds.

Remediation

Vendor Solution
