UniData: Uncontrolled Resource Consumption
CVE-2023-28507 is a critical-severity uncontrolled resource consumption vulnerability in UniData from Rocket Software, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 8.2.43.3003 as the first without the flaw, so updating UniData to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.92% chance of exploitation within 30 days, higher than 61% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update UniData to 8.2.43.3003 or a later version.
- Update UniVerse to 11.3.5.1001 or 12.2.1.2002, whichever matches your release line, or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Rocket Software UniData versions prior to 8.2.4 build 3003 and UniVerse versions prior to 11.3.5 build 1001 or 12.2.1 build 2002 suffer from a memory-exhaustion issue, where a decompression routine will allocate increasing amounts of memory until all system memory is exhausted and the forked process crashes.

The underlying weakness: Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource.
How developers prevent this class of flaw
- Ensure that protocols have specific limits of scale placed on them.
- Ensure that all failures in resource allocation place the system into a safe posture.
