Product | Affected Versions
Avigilon ACM | v7.10.0.20
How the Exploit Works
The exploit works by injecting malicious code into a crafted Excel file which is then uploaded to the /id_profiles endpoint of the Avigilon ACM v7.10.0.20. Since the system does not adequately sanitize the CSV file inputs, the injected code gets executed, potentially leading to system compromise or data leakage. The high severity score of 9.8 underscores the significant impact and ease of exploit.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited:
POST /id_profiles HTTP/1.1
Host: target.example.com
Content-Type: application/vnd.ms-excel
DATA:
C12: =cmd|'/C calc'!A0In this example, the exploit uses a standard formula injection technique to call the command line calculator application, which demonstrates the ability to execute arbitrary commands on the system.
Recommended Mitigation
The most effective mitigation for this vulnerability is to apply the vendor-patched update. If that is not immediately possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation. These tools can help detect and block malicious payloads, mitigating the immediate risk. However, these should only be seen as temporary solutions until the vendor patch can be applied.
