CVE-2023-45161· NVD / CVE Program· CNA 1E

1E-Exchange-URLResponseTime instruction before v20.1 allows arbitrary code execution

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.82% (FIRST EPSS); higher than 57.1% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: 1E Platform 20.1.
  • Severity is disputed: the assigning authority (CNA) scores it 9.9, NVD 7.2.

Low priority for now. Upgrade to 1E Platform 20.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The 1E-Exchange-URLResponseTime instruction that is part of the Network product pack available on the 1E Exchange does not properly validate the URL parameter, which allows for a specially crafted input to perform arbitrary code execution with SYSTEM permissions. This instruction only runs on Windows clients. To remediate this issue download the updated Network product pack from the 1E Exchange and update the 1E-Exchange-URLResponseTime instruction to v20.1 by uploading it through the 1E Platform instruction upload UI
