Summary

CVE-2023-54345 is a high-severity Code Injection (CWE-94) vulnerability in Frappe Erpnext. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 46th percentile by exploit likelihood (below the median); 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.

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

CVE-2023-54345 is a sandbox escape vulnerability in the RestrictedPython component used by Frappe Framework's ERPNext version 13.4.0. The flaw allows authenticated users with the System Manager role to bypass sandbox restrictions and execute arbitrary code through frame introspection in server scripts.

Attackers with System Manager privileges can exploit this by creating a server script via the /app/server-script endpoint. They access the gi_frame attribute to traverse the call stack and invoke functions such as os.popen, enabling execution of system commands. This results in high-impact confidentiality, integrity, and availability violations, as reflected in the CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and mapped to CWE-94 (Code Injection).

References point to the ERPNext site, Frappe Framework documentation on server scripting, a GitHub gist, the Frappe repository, and the vulnerable safe_exec.py source file at line 42 in v13.4.0, which handles the RestrictedPython execution environment.

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.
