Summary

CVE-2024-0692 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Solarwinds Security Event Manager. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The SolarWinds Security Event Manager is affected by CVE-2024-0692, a remote code execution vulnerability rated 8.8 CVSS that stems from deserialization of untrusted data (CWE-502). The flaw resides in the product’s service and permits unauthenticated abuse over an adjacent network.

An attacker with no credentials or user interaction can send crafted input to the service, resulting in arbitrary code execution that compromises confidentiality, integrity, and availability on the affected system.

SolarWinds has published security advisories and release notes for SEM 2023.4.1 that address the issue; administrators should apply the referenced update to remediate the vulnerability.

The CVE carries a high exploitation probability, with an EPSS score currently at 0.7830 and a recorded peak of 0.8527.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can uncover deserialization flaws before deployment.

SI-10 Information Input Validation good match

Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.

SI-7 Software, Firmware, and Information Integrity partial match

Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 none match
blocks

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.
