A cross-site scripting (XSS) vulnerability in Proxmox Virtual Environment (PVE) 9.x 5.1.8 and Proxmox Virtual Environment (PVE) 8.x 4.3.16 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload.
AnalysisAI
Cross-site scripting in Proxmox Virtual Environment (PVE) 8.x and 9.x allows an unauthenticated remote attacker to inject and execute arbitrary JavaScript in the browser of an authenticated PVE user who interacts with a crafted payload. The CVSS scope change (S:C) confirms the injected script executes outside the originating component's security context, enabling session hijacking, credential theft, or unauthorized management actions against the hypervisor web UI. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a victim user holding an active authenticated session in the Proxmox VE web management interface (port 8006) interact with a crafted payload - either by clicking a malicious link or by visiting a page containing the injected content (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS base score of 6.1 (Medium) reflects the constrained impact of limited confidentiality and integrity effects (C:L/I:L) despite a favorable attack vector (AV:N/AC:L/PR:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies a Proxmox VE deployment and discovers a URL parameter or input field in the web UI that reflects unsanitized user input. The attacker crafts a malicious URL embedding a JavaScript payload and delivers it via phishing email or forum post to a PVE administrator who is actively logged in. … |
| Remediation | No exact patched version is identifiable from the available intelligence - the Proxmox forum advisory at https://forum.proxmox.com/threads/proxmox-virtual-environment-security-advisories.149331/post-849973 should be consulted for the definitive fixed package version and upgrade instructions. … Detailed patch versions, workarounds, and compensating controls in full report. |
