Descriptions

In “Dolibarr” application, v3.3.beta1_20121221 to v13.0.2 have “Modify” access for admin level users to change other user’s details but fails to validate already existing “Login” name, while renaming the user “Login”. This leads to complete account takeover of the victim user. This happens since the password gets overwritten for the victim user having a similar login name.

En la aplicación "Dolibarr", versiones v3.3.beta1_20121221 a v13.0.2, los usuarios de nivel de administrador presentan acceso a la función "Modify" para cambiar los datos de otros usuarios, pero no comprueba el nombre de "Login" ya existente, mientras cambia el nombre del usuario "Login". Esto conlleva a una toma de posesión completa de la cuenta del usuario víctima. Esto sucede porque la contraseña es sobreescrita para el usuario víctima que presenta un nombre de inicio de sesión similar.
