Summary

CVE-2026-7841 is a high-severity Code Injection (CWE-94) vulnerability in Com (inferred from references). Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 37.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Information input validation directly prevents code injection by sanitizing crafted HTTP POST requests to the ASWebCommon.srf endpoint.

SI-2 Flaw Remediation good match

prevent

Flaw remediation addresses the specific RCE vulnerability in Notification Settings through patching as per the vendor advisory.

AC-6 Least Privilege partial match

prevent

Least privilege restricts the assignment of System Setting permissions, reducing the attack surface for authenticated exploitation.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

attack.mitre.org →

T1059 Command and Scripting Interpreter Execution

Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

attack.mitre.org →

Why these techniques?

Remote code execution via crafted HTTP POST to public-facing web app endpoint (CWE-94 code injection) directly enables T1190 for exploitation of the exposed application and T1059 for resulting arbitrary command execution on the server.

NVD Description

A remote code execution vulnerability exists in Notification Settings on GeoVision GV-ASWeb 6.2.0. An authenticated user with System Setting permissions can execute arbitrary commands on the server by sending a crafted HTTP POST request to the ASWebCommon.srf backend endpoint to…

bypass the frontend restrictions.

Deeper analysisAI

CVE-2026-7841 is a remote code execution vulnerability in the Notification Settings component of GeoVision GV-ASWeb version 6.2.0. It allows an authenticated user with System Setting permissions to execute arbitrary commands on the server by sending a crafted HTTP POST request to the ASWebCommon.srf backend endpoint, bypassing frontend restrictions. The vulnerability is classified under CWE-94 (Code Injection) with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for complete server compromise.

An attacker requires network access and low-privilege authentication as a user with System Setting permissions to exploit this flaw. By crafting and sending a malicious POST request to the vulnerable endpoint, the attacker can achieve remote code execution, granting high-impact control over confidentiality, integrity, and availability of the affected server. No user interaction is needed, and the attack has low complexity, making it accessible to moderately skilled adversaries with valid credentials.
