Overview<\/strong><\/p>\n

The cybersecurity community is currently grappling with a critical vulnerability, CVE-2025-54955, that affects OpenNebula Community Edition (CE) versions prior to 7.0.0 and Enterprise Edition (EE) versions before 6.10.3. This vulnerability stems from an exploitable FireEdge race condition that can lead to full account takeover, posing a significant risk to OpenNebula users. Given the severity and potential impact of this vulnerability<\/a>, it is crucial for users and administrators to understand its workings, the risks it poses, and the measures required to mitigate it.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-54955
\nSeverity: Critical with CVSS score of 8.1
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Full system compromise<\/a> or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

OpenNebula Community Edition<\/a> (CE) | Before 7.0.0
\nOpenNebula Enterprise Edition<\/a> (EE) | Before 6.10.3<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability arises due to a race condition<\/a> in FireEdge, a component of OpenNebula. An attacker can exploit<\/a> this race condition to generate a valid JSON Web Token (JWT) for any user without needing their credentials. By gaining a valid JWT, the attacker can impersonate a legitimate user and take control of their account, leading to a full system<\/a> compromise or significant data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how an attacker might exploit this vulnerability. The example uses a simple HTTP request to exploit the race condition<\/a>.<\/p>\n

POST \/fireedge\/generateJWT HTTP\/1.1\nHost: target.opennebula.com\nContent-Type: application\/json\n{ \"user_id\": \"target_user_id\" }<\/code><\/pre>\n
In this example, an attacker sends a POST request<\/a> to the `\/fireedge\/generateJWT` endpoint with a target user’s ID. If the race condition is successfully exploited, the server responds with a valid<\/a> JWT for the user, which the attacker can then use to take over the user’s account.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users are strongly advised to apply the vendor patch as soon as possible to fix this critical vulnerability<\/a>. For those unable to apply the patch immediately, deploying a web<\/a> application firewall (WAF) or intrusion detection system (IDS) can provide a temporary mitigation against potential attacks. However, these measures are only temporary and do not fully resolve the vulnerability, so applying the vendor patch should be the top priority.<\/p>\n","protected":false},"excerpt":{"rendered":"
