Apache StreamPipes: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)
CVE-2024-29868 is a critical-severity use of cryptographically weak pseudo-random number generator (PRNG) vulnerability in Apache StreamPipes from Apache, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Apache StreamPipes versions: 0.69.0 through 0.93.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 6% chance of exploitation within 30 days, which is in the top 6.56% of all scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update streampipes to 0.95.0 or a later version.
- Read the advisory on lists.apache.org for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Apache | Apache StreamPipes | 0.69.0 through 0.93.0 | Not stated |
| Apache | streampipes | 0.69.0 up to, but not including, 0.95.0 | 0.95.0 |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.

Official description
Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) vulnerability in Apache StreamPipes user self-registration and password recovery mechanism. This allows an attacker to guess the recovery token in a reasonable time and thereby to take over the attacked user's account. This issue affects Apache StreamPipes: from 0.69.0 through 0.93.0. Users are recommended to upgrade to version 0.95.0, which fixes the issue.

The underlying weakness: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)
The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong.
How developers prevent this class of flaw
- Use functions or hardware which use a hardware-based random number generation for all crypto. This is the recommended solution. Use CyptGenRandom on Windows, or hw_rand() on Linux.
