CVE-2026-5707: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in AWS Research and Engineering Studio (RES)
CVE-2026-5707 is a high-severity OS command injection vulnerability in AWS Research and Engineering Studio (RES) versions 2025. 03 through 2025. 12. 01. It arises from unsanitized input in the handling of virtual desktop session names, allowing a remote authenticated user to execute arbitrary commands as root on the virtual desktop host. AWS has released a fix in RES version 2026. 03 and/or a corresponding mitigation patch. Since RES is a cloud service, AWS manages remediation server-side. No known exploits are reported in the wild at this time.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-5707) involves improper neutralization of special elements in OS commands (CWE-78) within AWS Research and Engineering Studio (RES). Specifically, the virtual desktop session name input is not sanitized, enabling a remote authenticated actor to inject OS commands executed with root privileges on the virtual desktop host. Affected versions include RES 2025.03 through 2025.12.01. AWS has provided a patch in version 2026.03 and/or a mitigation patch. As RES is a cloud-hosted service, AWS typically applies fixes server-side. The CVSS v3.1 score is 8.8, indicating high severity with network attack vector, low attack complexity, requiring privileges, no user interaction, and full confidentiality, integrity, and availability impact.
Potential Impact
Successful exploitation allows a remote authenticated user to execute arbitrary commands as root on the virtual desktop host, leading to complete compromise of the host's confidentiality, integrity, and availability. This could result in full control over the virtual desktop environment and potentially impact other hosted resources. No known active exploits have been reported.
Mitigation Recommendations
AWS has released a patch in RES version 2026.03 and/or a corresponding mitigation patch. Since RES is a cloud service, AWS manages remediation for this vulnerability server-side. Users should verify with the AWS security bulletin (https://aws.amazon.com/security/security-bulletins/2026-014-aws/) to confirm that their environment has been updated or patched accordingly. No additional user action is required if the environment is up to date.
