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 vulnerability CVE-2023-35184 is a remote code execution flaw in SolarWinds Access Rights Manager stemming from deserialization of untrusted data (CWE-502). It received a CVSS 3.1 score of 8.8 reflecting network-adjacent attack vector, low attack complexity, and no required authentication or user interaction, with high impact across confidentiality, integrity, and availability.

An unauthenticated attacker can exploit the issue by abusing a SolarWinds service to execute arbitrary code on the affected system, potentially gaining full control over the Access Rights Manager instance and any data or resources it manages.

SolarWinds addressed the flaw in Access Rights Manager version 2023.2.1, as detailed in the vendor's release notes and accompanying security advisory.

The associated EPSS score has remained flat at 0.1060 with no material rise after disclosure.

PR.PS-02 none match
prevents

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prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

finds

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.

prevents

Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.

finds

Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.

none

Mandatory malware scanning of data received over networks or storage media intercepts malicious serialized payloads before they are deserialized by the target application.
