SolarWinds Serv-U was found to be affected by a stored cross-site scripting vulnerability that could lead to session hijacking or information disclosure from an administrator account.
AnalysisAI
Stored cross-site scripting in SolarWinds Serv-U enables session hijacking and information disclosure from administrator accounts via malicious script persistence in the application. The vulnerability requires a high-privileged attacker to inject the payload, which then executes in the browser context of any administrator who views the poisoned content - a classic privilege-boundary-crossing XSS pattern confirmed by the CVSS scope-change flag. …

Vulnerability AssessmentAI
| Exploitation | The attacker must already hold a high-privilege administrator account on the SolarWinds Serv-U instance (PR:H per the CVSS vector) sufficient to write data into the field containing the stored XSS payload. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.2 reflects a meaningful but bounded risk profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has compromised or legitimately holds a high-privilege Serv-U administrator account injects a JavaScript payload into a field that is stored by the application and rendered in the administrative interface - for example, a filename, user comment, or configuration label. When a peer administrator subsequently navigates to the affected view, their browser executes the script, which reads the administrator's session cookie and exfiltrates it to an attacker-controlled endpoint. … |
| Remediation | The primary fix is to upgrade SolarWinds Serv-U to version 2026.3, as indicated by the release notes reference at https://documentation.solarwinds.com/en/success_center/servu/content/release_notes/servu_2026-3_release_notes.htm. … Detailed patch versions, workarounds, and compensating controls in full report. |
