CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2024-38396 is a critical-severity Code Injection (CWE-94) vulnerability in Iterm2 Iterm2. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 25% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-38396 affects iTerm2 versions 3.5.x prior to 3.5.2. The flaw stems from unfiltered handling of an escape sequence that reports the window title when the application's built-in tmux integration is active, which is enabled by default. This permits code injection into the terminal and is tracked under CWE-94 with a CVSS 3.1 score of 9.8.
An attacker can supply a malicious escape sequence through a remote host, SSH session, or any untrusted output rendered in the terminal. Because tmux integration processes the sequence without sanitization, the attacker can achieve arbitrary code execution on the user's system without requiring authentication or user interaction.
The referenced commit fc60236a914d63fb70a5c632e211203a4f1bd4dd and the iTerm2 3.5.2 release on the project downloads page address the issue by filtering the escape sequence. The oss-security advisory and the detailed write-up at vin01.github.io both recommend upgrading immediately and disabling tmux integration until patches are applied if downgrades are not feasible.
EPSS scores have remained near 0.10 with only minor fluctuation between current and peak values, indicating no pronounced post-disclosure exploitation surge.

Vulnerability Data
An issue was discovered in iTerm2 3.5.x before 3.5.2. Unfiltered use of an escape sequence to report a window title, in combination with the built-in tmux integration feature (enabled by default), allows an attacker to inject arbitrary code into the…

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
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 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

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.
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.
