Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly remediates the CSV injection flaw in Avigilon ACM v7.10.0.20's /id_profiles endpoint by identifying, testing, and deploying patches to prevent arbitrary code execution.

prevent

Validates all supplied Excel files and inputs to the /id_profiles endpoint to reject crafted payloads that exploit the CSV injection vulnerability.

prevent

Implements memory protections to mitigate arbitrary code execution on the server even if a crafted Excel file bypasses input validation.

MITRE ATT&CK Enterprise TechniquesAI

T1204.002 Malicious File Execution
An adversary may rely upon a user opening a malicious file in order to gain execution.
Why these techniques?

CSV injection in /id_profiles endpoint enables injecting malicious formulas into exported CSV/Excel files, executing arbitrary code when opened by users in spreadsheet software (T1204.002: Malicious File).

NVD Description

A CSV injection vulnerability in the /id_profiles endpoint of Avigilon ACM v7.10.0.20 allows attackers to execute arbitrary code via suuplying a crafted Excel file.

Deeper analysisAI

CVE-2025-56267 is a CSV injection vulnerability in the /id_profiles endpoint of Avigilon ACM version 7.10.0.20. The flaw allows attackers to execute arbitrary code by supplying a crafted Excel file. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-1236. The vulnerability was published on 2025-09-08.

Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. By targeting the /id_profiles endpoint with a crafted Excel file, an attacker achieves arbitrary code execution, resulting in high confidentiality, integrity, and availability impacts.

Exploit details, including proof-of-concept code for the CSV injection, are documented in GitHub repositories at https://github.com/nikolas-ch/CVEs/blob/main/AvigilonACM_v7.10.0.20/CSV_Injection/CSV_Injection.txt and related directories. No official advisories or patches are referenced in available information.
