CVE-2026-72589: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in alseambusher crontab-ui
CVE-2026-72589 is a critical OS command injection vulnerability in alseambusher's crontab-ui versions prior to 0.4.3. It allows unauthenticated remote attackers to execute arbitrary system commands by importing a crafted crontab database file via the POST /import endpoint, which accepts arbitrary .db files without validation and overwrites the application database.
AI Analysis
Technical Summary
This vulnerability (CWE-78) exists in crontab-ui through version 0.4.2. The POST /import endpoint does not validate imported .db files, enabling unauthenticated remote attackers to craft malicious database files that lead to arbitrary OS command execution. This is due to improper neutralization of special elements used in OS commands, allowing attackers to execute system commands with the privileges of the application.
Potential Impact
Successful exploitation results in full system compromise with high confidentiality, integrity, and availability impact, as attackers can execute arbitrary commands remotely without authentication. This can lead to data theft, system manipulation, or denial of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the POST /import endpoint and avoid importing untrusted .db files.
