Published: 12 September 2024
Summary
CVE-2024-28991 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Solarwinds Access Rights Manager. Its CVSS base score is 9.0 (Critical).
Operationally, ranked in the top 3.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
SolarWinds Access Rights Manager (ARM) is affected by a remote code execution vulnerability tracked as CVE-2024-28991. The flaw stems from improper handling consistent with CWE-502 and permits an authenticated user to abuse the service, resulting in arbitrary code execution on the target system. It carries a CVSS 3.1 score of 9.0 reflecting an adjacent-network attack vector, low attack complexity, low privileges required, and high impact across confidentiality, integrity, and availability with changed scope.
An authenticated attacker positioned on the same network segment can exploit the weakness without user interaction to achieve remote code execution. Successful exploitation grants the attacker the ability to run arbitrary commands with the privileges of the ARM service, potentially leading to full compromise of the affected system and any connected resources within its scope.
SolarWinds has published an advisory and release notes for ARM version 2024.3.1 that address the issue and provide mitigation guidance. The current EPSS score of 0.3090 matches its recorded peak, indicating sustained exploitation interest following disclosure.

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.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
