CVE-2025-34511: Sitecore PowerShell Extension RCE via Unrestricted Upload

Noroxi assessment

Priority: Plan (action score 44/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 30.4% (FIRST EPSS); higher than 98.2% of all records.
  • Anyone who can reach it over the internet 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

Sitecore PowerShell Extensions, an add-on to Sitecore Experience Manager (XM) and Experience Platform (XP), through version 7.0 is vulnerable to an unrestricted file upload issue. A remote, authenticated attacker can upload arbitrary files to the server using crafted HTTP requests, resulting in remote code execution.
