AI Analysis
Technical Summary
This vulnerability in Vaelsys VaelsysV4 affects the web interface component by using a weak hash function when handling the xajaxargs argument in /grid/vgrid_server.php. The weakness could be exploited remotely, though the attack complexity is high and requires low privileges. The CVSS 4.0 score is 2.3, indicating low severity. Public exploit code is available. The vendor has released fixed versions 5.1.1 and 5.4.1 that address this issue.
Potential Impact
The use of a weak hash may allow an attacker to compromise data integrity or authentication mechanisms relying on this hash. However, the low CVSS score and high attack complexity indicate limited impact. The vulnerability can be exploited remotely without user interaction but requires low privileges and is difficult to exploit. Public exploit availability increases risk but the overall impact remains low.
Mitigation Recommendations
Upgrade Vaelsys VaelsysV4 to version 5.1.1 or 5.4.1 to remediate this vulnerability. These versions contain fixes that replace the weak hash usage. No other mitigation is indicated or required.
