Summary

CVE-2024-21689 is a high-severity Code Injection (CWE-94) vulnerability in Atlassian Bamboo. Its CVSS base score is 8.0 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 16% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-21689 is a high-severity remote code execution vulnerability affecting Atlassian Bamboo Data Center and Server versions 9.1.0 through 9.6.0. It carries a CVSS 3.1 score of 8.0 and stems from improper control of code generation, enabling an authenticated attacker to execute arbitrary code on the affected instance.

An authenticated attacker with user interaction can exploit the flaw over the network to achieve high impacts on confidentiality, integrity, and availability by running arbitrary code within the Bamboo environment. The vulnerability was identified through Atlassian's bug bounty program.

Atlassian advises customers to upgrade Bamboo Data Center and Server to the latest release or to a fixed version such as 9.2.17 or later for the 9.2 branch and 9.6.5 or later for the 9.6 branch, with release notes and downloads available from the vendor's sites. The current EPSS score of 0.37 with a recorded peak of 0.42 does not indicate a pronounced post-disclosure climb from a low baseline.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
