Limited remote code execution with privilege of a NetworkService Account access
Noroxi assessment
Priority: Plan (action score 54/100)
- CISA has confirmed exploitation in the wild (Aug 25, 2025). Remediation deadline for US federal agencies: Sep 15, 2025.
- Probability of exploitation in the next 30 days: 14.6% (FIRST EPSS); higher than 96.6% 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.
- Fixed version: Citrix Session Recording Citrix Session Recording 24.5.200.8, CU1 hotfix 24.02.1200.16, CU5 hotfix 22.03.5100.11.

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.
