Memory Safety in Rocketsoftware Universe ≤ 11.3.5
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-28504 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Rocketsoftware Universe. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 28% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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 contain a stack-based buffer overflow vulnerability tracked as CVE-2023-28504. The flaw, assigned CWE-120 and CWE-787, resides in the UniRPC server component and carries a CVSS 3.1 score of 9.8 reflecting network attack vector, low complexity, and no required privileges or user interaction.
An unauthenticated remote attacker can send specially crafted network requests to trigger the overflow, resulting in arbitrary code execution with root privileges on the affected server. This grants complete control over the database environment, including the ability to read, modify, or delete data and potentially pivot to other systems.
Public advisories from Rapid7 detail that the vulnerabilities were fixed in the listed builds of UniData and UniVerse and recommend immediate upgrade of the UniRPC server to eliminate the buffer overflow exposure.
The associated EPSS score rose from a low baseline to a peak of 0.0514 before receding to the current value of 0.0196, indicating measurable post-disclosure exploitation interest.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Platform-independent managed code eliminates the need for unchecked native buffer copies that are the root cause of classic buffer overflows.
Out-of-bounds writes that corrupt control flow or inject shellcode are rendered non-executable by the same memory protections.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Vulnerability identification processes such as code review or scanning detect classic buffer overflows before exploitation.
Routine patching replaces vulnerable code containing unchecked buffer copies with corrected versions.
Secure development practices directly enforce bounds checking and input validation that prevent classic buffer overflows.
