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

SolarWinds Access Rights Manager (ARM) is affected by CVE-2024-23478, a remote code execution vulnerability that arises from deserialization of untrusted data. The flaw carries a CVSS 3.1 score of 8.0 and permits an authenticated user to abuse a SolarWinds service, resulting in arbitrary code execution on the target system.

An attacker with low privileges and adjacent-network access can exploit the issue without user interaction to obtain full control over confidentiality, integrity, and availability on the affected installation. The EPSS score has remained stable at 0.6186 since disclosure.

SolarWinds has published an advisory for the vulnerability at the referenced URL. No information on real-world exploitation activity is provided in the available data.

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cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.
