1. What is this vulnerability and why does it matter?

This vulnerability, identified as CVE-2024-50550, is an Incorrect Privilege Assignment flaw within the LiteSpeed Technologies LiteSpeed Cache (litespeed-cache) product. It enables Privilege Escalation, meaning an attacker with lower privileges could exploit this flaw to gain higher-level access to the affected system. This matters significantly because privilege escalation can lead to complete system compromise, unauthorized data access, modification, or destruction, and potentially full control over the compromised environment, bypassing security controls and escalating the impact of any initial breach.

2. What are the CVSS score, severity level, and disclosure details?

The CVSS score for this vulnerability is 9.8, which designates it as a Critical severity level. The vulnerability was published on 2024-10-29 at 09:57:24 UTC and was last modified on 2026-04-28 at 16:10:32 UTC.

3. Which products, vendors, systems, and versions are affected?

The affected vendor is LiteSpeed Technologies. The vulnerable product is LiteSpeed Cache, specifically the 'litespeed-cache' component. This issue affects all versions of LiteSpeed Cache up to and including version 6.5.1.

4. What is the technical root cause and attack vector?

The technical root cause of this vulnerability is an Incorrect Privilege Assignment (CWE-266). This means that a specific function or resource within the LiteSpeed Cache component can be accessed or manipulated by a user or process that does not have the necessary authorization. The primary attack vector is Privilege Escalation, where an attacker leverages this misconfiguration to elevate their access rights on the system.

5. How can this vulnerability be exploited?

This vulnerability can be exploited by an attacker to achieve privilege escalation due to incorrect privilege assignments within the LiteSpeed Cache. While the exact exploit steps are not detailed in the provided CVE data, generally, an attacker would identify a component or function within the LiteSpeed Cache that incorrectly allows lower-privileged users to perform actions typically reserved for administrators or higher-privileged accounts. By interacting with this component, the attacker can then escalate their privileges to a higher level.

6. What mitigation steps and patches are available?

To mitigate this vulnerability, users should update their LiteSpeed Cache installation to a version greater than 6.5.1. Versions newer than 6.5.1 are expected to contain the necessary patches to address the Incorrect Privilege Assignment flaw.

7. How can vulnerable systems be detected?

Vulnerable systems can be detected by checking the installed version of the LiteSpeed Cache plugin. Any installation of LiteSpeed Cache with a version number less than or equal to 6.5.1 is considered vulnerable to CVE-2024-50550.

10. What public intelligence references and advisories exist?

The primary public intelligence reference is CVE-2024-50550 itself. Additional details and advisories may be available from LiteSpeed Technologies or common vulnerability databases, typically linked from the CVE entry. The vulnerability was published on 2024-10-29 and modified on 2026-04-28.

11. What is the risk assessment and urgency level?

Given the CVSS score of 9.8 and its classification as a Privilege Escalation vulnerability due to Incorrect Privilege Assignment, the risk assessment for CVE-2024-50550 is Critical. The urgency level for patching and remediation is High, as successful exploitation could lead to full system compromise and significant security breaches. Organizations should prioritize updating affected systems immediately.
