CWE-327

Description

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android, through 0.0.80w for Web, and through 0.0.86 for Desktop. To encrypt messages, AES in CBC mode is used with a pseudo-random secret. This secret and the IV are generated with math.random() in previous versions and with CryptoJS.lib.WordArray.random() in newer versions, which uses math.random() internally. This is not cryptographically strong.

Affected configurations

• stashcat heinekingmedia (<= 1.7.5) • stashcat heinekingmedia (<= 0.0.80w) • stashcat heinekingmedia (<= 0.0.86w)
