CVE-2026-25861
QloApps 1.7.0 Weak Password Hashing via MD5 in Tools.php
Description
QloApps through 1.7.0, fixed in commit 64e9722, contains a weak cryptographic algorithm vulnerability that allows attackers to compromise user credentials by exploiting the use of MD5 for password hashing in the Tools::encrypt() function within classes/Tools.php, which concatenates a static cookie key with the supplied password. Attackers can perform offline brute-force attacks against the MD5 hashes, with the risk compounded by auto-generated 8-character passwords assigned during guest-to-customer account conversion in classes/Customer.php, making credential recovery trivial.

Action Type Old Value New Value Added Translation Title: QloApps, Description: QloApps hasta 1.7.0, corregido en el commit 64e9722, contiene una vulnerabilidad de algoritmo criptográfico débil que permite a los atacantes comprometer las credenciales de usuario al explotar el uso de MD5 para el hash de contraseñas en la función Tools::encrypt() dentro de classes/Tools.php, que concatena una clave de cookie estática con la contraseña proporcionada. Los atacantes pueden realizar ataques de fuerza bruta offline contra los hashes MD5, con el riesgo agravado por contraseñas de 8 caracteres autogeneradas asignadas durante la conversión de cuenta de invitado a cliente en classes/Customer.php, haciendo trivial la recuperación de credenciales. -
