The EPSS score of less than 1% suggests a low probability of exploitation in the wild, and the issue is not present in CISA\u2019s KEV catalog. However, the requirement of authentication and access to the upload endpoint means that intruders who gain valid credentials or exploit weak access controls can leverage the flaw. Because the exploit relies on an uploaded web.config file, an attacker can connect via the internet to the API and perform the attack once authenticated, making it a remote code execution risk that could affect all users with valid credentials."}}}}, "created": "2026-03-06T15:18:19.248829+00:00", "title": "Remote Code Execution via Improper Validation of Uploaded web.config in Aranda Service Desk API", "updated": "2026-04-22T11:30:15.373799+00:00", "vendors": ["arandasoft", "arandasoft$PRODUCT$aranda_service_desk_web_edition"]}
