projectsend: Use of Insufficiently Random Values
CVE-2024-7659 is a high-severity use of insufficiently random values vulnerability in projectsend, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected projectsend versions: r1605. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.79% chance of exploitation within 30 days, higher than 57% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of projectsend you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
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.

The underlying weakness: Use of Insufficiently Random Values
The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.
How developers prevent this class of flaw
- 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.
- Consider a PRNG that re-seeds itself as needed from high quality pseudo-random output sources, such as hardware devices.
- Use products or modules that conform to FIPS 140-2 to avoid obvious entropy problems. Consult FIPS 140-2 Annex C (Approved Random Number Generators).
