A vulnerability, which was classified as problematic, was found in projectsend up to r1605. Affected is the function generate_random_string of the file includes/functions.php of the component Password Reset Token Handler. The manipulation leads to insufficiently random values. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. Upgrading to version r1720 is able to address this issue. The name of the patch is aa27eb97edc2ff2b203f97e6675d7b5ba0a22a17. It is recommended to upgrade the affected component.

Weakness

The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.

Affected Software

Potential Mitigations

• Use a well-vetted algorithm that is currently considered to be strong by experts in the field, and select well-tested implementations with adequate length seeds.
• In general, if a pseudo-random number generator is not advertised as being cryptographically secure, then it is probably a statistical PRNG and should not be used in security-sensitive contexts.
• Pseudo-random number generators can produce predictable numbers if the generator is known and the seed can be guessed. A 256-bit seed is a good starting point for producing a “random enough” number.
