CVE-2026-10550: Command Injection in elunez eladmin Deployment Module

Technical summary

CVE-2026-10550 is a command injection flaw (CWE-74, CWE-77) in the App.java file of eladmin's Application Deployment Module. The uploadPath parameter is not properly sanitized, allowing an authenticated attacker to craft malicious input that breaks out of intended command context and executes arbitrary system commands with the privileges of the application. The attack surface is network-accessible, making it remotely exploitable by any user with valid authentication credentials.

Business impact

Successful exploitation could allow an authenticated attacker to execute arbitrary commands on servers running vulnerable eladmin instances. This may lead to data theft, system compromise, lateral movement within internal networks, installation of malware or backdoors, or denial of service. Organizations using eladmin for deployment management face elevated risk if the system processes untrusted file uploads or if multiple users have authenticated access.

Affected systems

elunez eladmin versions 2.7 and earlier are affected. The vulnerability resides in the Application Deployment Module, specifically in the file handling logic of App.java. Any deployment environment relying on this component for application management is at risk.

Exploitability

Exploitation is feasible and does not require elevated privileges beyond standard user authentication. The attack vector is network-based with low complexity—no special conditions or user interaction is needed once an attacker is authenticated. Public exploit code availability significantly lowers the barrier to weaponization. CVSS 3.1 score of 6.3 (MEDIUM severity) reflects the requirement for prior authentication, which provides some organizational control but does not eliminate risk in environments with permissive access policies.

Remediation

Upgrade elunez eladmin to a patched version released after 2.7 once available. Verify the vendor advisory for specific version guidance. Until patching is possible, implement strict access controls limiting authenticated users who can access the Application Deployment Module. Monitor uploadPath parameter usage and network traffic for signs of exploitation. Consider disabling the deployment module if it is not actively required.

Patch guidance

Contact elunez or monitor their official repository and security announcements for a patch release addressing this command injection. The vendor has been informed but has not yet responded publicly; verify against the official advisory when available. Apply patches as soon as they are released, prioritizing systems in production environments or exposed to untrusted networks.

Detection guidance

Monitor application logs and system command execution for suspicious uploadPath values, especially those containing shell metacharacters (pipes, semicolons, backticks, command substitution syntax). Network detection systems should flag authentication attempts followed by unusual POST or PUT requests to deployment endpoints. Endpoint detection and response (EDR) solutions should alert on unexpected child process spawning from the application runtime. Review file integrity monitoring for unauthorized changes to system files following deployment module access.

Why prioritize this

Although this vulnerability is classified as MEDIUM severity and does not yet appear on the CISA KEV list, the combination of public exploit availability, authenticated-but-low-friction access, and remote code execution capability warrants prompt attention. Organizations should prioritize patching or mitigation based on the number of eladmin deployments, the sensitivity of systems they manage, and the breadth of user access to the deployment module.

Risk score, explained

CVSS 3.1 score of 6.3 reflects a MEDIUM severity rating anchored by the requirement for prior authentication (PR:L), which mitigates the overall impact compared to an unauthenticated vector. However, the low attack complexity (AC:L), network accessibility (AV:N), and impact on confidentiality, integrity, and availability (C:L/I:L/A:L) elevate the practical risk. Public exploit availability and lack of vendor responsiveness further increase real-world concern.
