Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Stored XSS in OpenPLC ScadaBR. ๐ **Consequences**: Attackers inject malicious scripts via `system_settings.shtm`. Victims executing these scripts face session hijacking, data theft, or defacement.โฆ
๐ก๏ธ **Root Cause**: Lack of input validation/sanitization on the `system_settings.shtm` page. ๐ **Flaw**: Allows storage of executable JavaScript in system settings, triggering execution upon page load.โฆ
๐ฆ **Affected Products**: OpenPLC ScadaBR. ๐ฅ๏ธ **Versions**: Linux 0.9.1 & Windows 1.12.4. ๐ **Vendor**: n/a (Open Source). โ ๏ธ Only these specific versions are confirmed vulnerable.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Actions**: Run arbitrary JavaScript in victim's browser. ๐พ **Data**: Steal cookies, session tokens, or sensitive SCADA data. ๐ **Privileges**: Execute actions as the logged-in user.โฆ
๐ **Auth**: Likely requires access to `system_settings.shtm`. โ๏ธ **Config**: Needs ability to modify system settings. ๐ **Threshold**: Medium. If admin access is compromised, exploitation is trivial.โฆ
๐ฅ **Exp**: Video PoC available at `youtu.be/Xh6LPCiLMa8`. ๐ข **Status**: Publicly demonstrated. ๐ **Wild Exp**: Forum discussions confirm awareness. โ ๏ธ Active exploitation risk is real.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for `system_settings.shtm` endpoint. ๐งช **Test**: Attempt to inject `<script>` tags into settings fields. ๐ก **Scan**: Look for OpenPLC ScadaBR signatures. ๐ Verify if input is sanitized before storage.
Q8Is it fixed officially? (Patch/Mitigation)
๐ ๏ธ **Patch**: Data does not list an official CVE patch. ๐ **Published**: June 11, 2021. ๐ **Status**: Users must check vendor forums or update to newer, unlisted versions.โฆ
๐ฅ **Urgency**: HIGH. ๐ญ **Context**: Industrial systems are high-value targets. ๐ **Risk**: Stored XSS can lead to full system compromise. ๐จ **Action**: Patch immediately or apply strict network segmentation.โฆ
