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.

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.

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.
Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.
Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
Mandatory malware scanning of data received over networks or storage media intercepts malicious serialized payloads before they are deserialized by the target application.
