CVE-2024-7035 — MEDIUM (CVSS 6.9) AI Security Vulnerability

CISO Take

Any authenticated admin of open-webui ≤ 0.3.8 can have their entire RAG knowledge base, AI memory, and uploaded documents silently wiped by visiting a malicious page. CSRF via GET means no user interaction beyond normal browsing is required. Upgrade immediately; if on-prem deployment, restrict access to internal networks as interim mitigation.

Risk Assessment

CVSS 6.9 Medium understates operational impact for AI deployments. EPSS 0.0004 indicates low active exploitation, but the attack is trivial to execute — a single img tag or iframe suffices. The PR:H in the vector reflects that the victim must be a privileged user, not that the attacker needs privileges. Data destruction of RAG databases represents irreversible loss if backups are absent. Organizations running open-webui as an enterprise LLM interface with curated knowledge bases face disproportionate operational risk.

Recommended Action

5 steps

Upgrade open-webui to a version > 0.3.8.
If upgrade is not immediately possible: place the instance behind a VPN or internal network boundary, preventing external CSRF triggers.
Configure SameSite=Strict or SameSite=Lax on session cookies to block cross-origin requests at the browser level.
Audit web server logs for unexpected GET requests to /rag/api/v1/reset*, /api/v1/memories/reset — zero-arg resets from unexpected sources indicate exploitation.
Verify backup strategy for RAG databases and uploaded documents; test restore procedure before deploying the fix.

Frequently Asked Questions

What is CVE-2024-7035?

Any authenticated admin of open-webui ≤ 0.3.8 can have their entire RAG knowledge base, AI memory, and uploaded documents silently wiped by visiting a malicious page. CSRF via GET means no user interaction beyond normal browsing is required. Upgrade immediately; if on-prem deployment, restrict access to internal networks as interim mitigation.

Is CVE-2024-7035 actively exploited?

No confirmed active exploitation of CVE-2024-7035 has been reported, but organizations should still patch proactively.

How to fix CVE-2024-7035?

1. Upgrade open-webui to a version > 0.3.8. 2. If upgrade is not immediately possible: place the instance behind a VPN or internal network boundary, preventing external CSRF triggers. 3. Configure SameSite=Strict or SameSite=Lax on session cookies to block cross-origin requests at the browser level. 4. Audit web server logs for unexpected GET requests to /rag/api/v1/reset*, /api/v1/memories/reset — zero-arg resets from unexpected sources indicate exploitation. 5. Verify backup strategy for RAG databases and uploaded documents; test restore procedure before deploying the fix.

Technical Details

NVD Description

In version v0.3.8 of open-webui/open-webui, sensitive actions such as deleting and resetting are performed using the GET method. This vulnerability allows an attacker to perform Cross-Site Request Forgery (CSRF) attacks, where an unaware user can unintentionally perform sensitive actions by simply visiting a malicious site or through top-level navigation. The affected endpoints include /rag/api/v1/reset, /rag/api/v1/reset/db, /api/v1/memories/reset, and /rag/api/v1/reset/uploads. This impacts both the availability and integrity of the application.

Exploitation Scenario

Attacker sends a phishing email to a known open-webui admin containing a link to a malicious page. The page includes an img tag with src pointing to https://internal-webui.corp/rag/api/v1/reset/db. When the admin loads the page on their corporate browser — already authenticated to open-webui — the browser automatically issues the GET request with the admin's session cookie attached. The RAG database is wiped silently. The admin sees no error; the next LLM query simply returns no context-grounded answers. The attacker achieves persistent degradation of the AI system without ever authenticating to it.
