CVE-2024-29868: Apache StreamPipes: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Recovery Token Generation

Should you act?

Critical and remotely reachable

No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
• EPSS 6.0%, percentile 93: FIRST’s model estimates a 6.0% chance of exploitation activity in the next 30 days, higher than 93% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes org.apache.streampipes:streampipes-resource-management (Maven) >= 0.69.0, < 0.95.0, fixed in 0.95.0. Check your lockfile, including transitive dependencies.

What it is

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.
