CVE-2024-28075· NVD / CVE Program· CNA SolarWinds

SolarWinds ARM Deserialization of Untrusted Data Remote Code Execution

Noroxi assessment

Priority: Plan (action score 55/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 78% (FIRST EPSS); higher than 99.5% of all records.
Someone on the same network segment can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

The SolarWinds Access Rights Manager was susceptible to Remote Code Execution Vulnerability. This vulnerability allows an authenticated user to abuse SolarWinds service resulting in remote code execution. We thank Trend Micro Zero Day Initiative (ZDI) for its ongoing partnership in coordinating with SolarWinds on responsible disclosure of this and other potential vulnerabilities.

Weakness class (CWE)

CWE-502 · Deserialization of Untrusted Data

CVSS vector

CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

nvd-primary

Root cause

Data received over the network is deserialized into the language’s native object format without verifying its source. Code paths inside the object can be triggered during deserialization.
