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.

finds

Security testing in development can detect formula injection but does not itself implement the mitigation.

prevents

Secure SDLC mandates input validation and output encoding that directly prevents formula injection in CSV exports.

prevents

Application security requirements include rules for safe CSV generation and handling of untrusted data.

prevents

Secure architecture principles encourage safe data export design but do not specifically address CSV formula neutralization.

prevents

Secure coding standards explicitly require neutralization of special characters when writing CSV files.
