CVE-2022-36633

Teleport 9.3.6 is vulnerable to Command injection leading to Remote Code Execution. An attacker can craft a malicious ssh agent installation link by URL encoding a bash escape with carriage return line feed. This url encoded payload can be used in place of a token and sent to a user in a social engineering attack. This is fully unauthenticated attack utilizing the trusted teleport server to deliver the payload.

The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.

CVE-2022-36633 has a CVSS score of 8.8 (High). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (8.3.17, 9.3.13, 10.1.2); upgrading removes the vulnerable code path.

1. What is CVE-2022-36633? CVE-2022-36633 is a high-severity improper input validation vulnerability in github.com/gravitational/teleport (go), affecting versions < 8.3.17. It is fixed in 8.3.17, 9.3.13, 10.1.2. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
2. How severe is CVE-2022-36633? CVE-2022-36633 has a CVSS score of 8.8 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of github.com/gravitational/teleport are affected by CVE-2022-36633? github.com/gravitational/teleport (go) versions < 8.3.17 is affected.
4. Is there a fix for CVE-2022-36633? Yes. CVE-2022-36633 is fixed in 8.3.17, 9.3.13, 10.1.2. Upgrade to this version or later.
5. Is CVE-2022-36633 exploitable, and should I be worried? Whether CVE-2022-36633 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2022-36633 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2022-36633?
   • Upgrade github.com/gravitational/teleport to 8.3.17 or later
   • Upgrade github.com/gravitational/teleport to 9.3.13 or later
   • Upgrade github.com/gravitational/teleport to 10.1.2 or later
