Research And Engineering Studio Res CVE-2026-5707

This vulnerability exploits CWE-78 (OS Command Injection) in the virtual desktop session name handling component of AWS Research and Engineering Studio, a cloud-based research computing environment. The affected software fails to sanitize user-controlled input from session names before passing them to underlying operating system commands executed on virtual desktop hosts. In command injection attacks, special shell metacharacters (such as semicolons, backticks, pipes, or command substitution syntax) embedded in untrusted input allow attackers to break out of the intended command context and execute arbitrary system commands. The CPE identifier (cpe:2.3:a:aws:research_and_engineering_studio_(res)) confirms this affects the RES product line specifically. The CVSS vector AV:N/AC:L/PR:L indicates network-accessible exploitation with low attack complexity requiring only low-privilege authentication, making this readily exploitable by any authenticated RES user. The root-level execution capability (implied by 'execute arbitrary commands as root') represents a complete compromise of the virtual desktop host, bypassing normal privilege separation.
