CVE-2017-11131

01.08.2017, 14:29

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. For authentication, the user password is hashed directly with SHA-512 without a salt or another key-derivation mechanism to enable a secure secret for authentication. Moreover, only the first 32 bytes of the hash are used. This allows for easy dictionary and rainbow-table attacks if an attacker has access to the password hash.

Common Weakness Enumeration

CWE-916 - Use of Password Hash With Insufficient Computational Effort
The software generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive.
