Remote code execution in Vaelsys 4.1.0 allows unauthenticated attackers to execute arbitrary OS commands via malicious xajaxargs parameters sent to the /tree/tree_server.php endpoint. Public exploit code exists for this vulnerability, and the vendor has not released a patch despite early notification. This network-accessible flaw poses immediate risk to exposed Vaelsys installations.
Improper authorization in Vaelsys VaelsysV4 4.1.0 exposes the User Creation Handler at /grid/vgrid_server.php to potential unauthorized user creation via remote network requests. A publicly available proof-of-concept demonstrates the technique, though the vendor formally disputes the finding, asserting the endpoint enforces authenticated administrative context and no unauthorized escalation is possible. EPSS stands at 0.12% (30th percentile), no CISA KEV listing exists, and the real-world exploitability remains contested - making this a low-confidence finding that nonetheless warrants verification by affected operators.
Weak cryptographic hashing (CWE-327) in VaelsysV4's PHP web interface exposes sensitive information to authenticated remote attackers who can manipulate the xajaxargs parameter of /grid/vgrid_server.php. Affected versions span the 5.1.0 and 5.4.0 release lines; patched releases 5.1.1 and 5.4.1 are available. No public exploit identified at time of analysis per CISA KEV, but a public proof-of-concept exists, and the EPSS score of 0.03% confirms very limited real-world exploitation activity to date.
OS command injection in Vaelsys VaelsysV4 (versions up to 5.1.0 and 5.4.0) allows remote unauthenticated attackers to execute arbitrary operating system commands via the xajaxargs parameter passed to the execute_DataObjectProc function in /grid/vgrid_server.php. The attack is fully remote, requires no authentication per the CVSS 4.0 PR:N metric, and a public proof-of-concept exploit is confirmed available on GitHub, raising the urgency of remediation. No active exploitation has been confirmed by CISA KEV at time of analysis, though an EPSS at the 75th percentile reflects non-trivial exploitation probability relative to the broader CVE population.
