Technical impact
A code injection flaw in the /api/system-update/import endpoint allows remote attackers to execute arbitrary code on servers running Travisun Opptrix 0.4.0. The vulnerability arises from unsanitized input that can be used to inject malicious scripting or command code, leading to full compromise of the affected system. This flaw is an injection weakness classified as CWE-74 and also involves improper code generation (CWE-94), which together expose the system to arbitrary code execution. The impact includes data loss, defacement, and further lateral movement by the attacker.
Affected Systems
The flaw is present only in the deprecated Travisun Opptrix 0.4.0 release. At the time of discovery the product was no longer supported and the maintainer had taken the project offline. No other versions are impacted, and the issue is specific to configurations using the public import endpoint.
Risk and Exploitability
The CVSS score of 6.9 classifies the risk as medium severity. This injection flaw (CWE-74) and code generation weakness (CWE-94) allow remote attackers to execute arbitrary code on exposed instances. Because the exploit is remote and publicly disclosed, an attacker can target any exposed instance of the endpoint. The EPSS score is not available and the vulnerability is not listed in the CISA KEV catalog, but the lack of updates increases the likelihood of exploitation through legacy deployments. The design flaw was originally intended for local testing environments, yet the vulnerability can still be triggered in remotely exposed installations.
