OS Command Injection in SabyasachiRana WebMap Affects Remote Scanning Feature

CVE-2026-90843

What is CVE-2026-90843?

CVE-2026-90843 is a critical security vulnerability identified in the SabyasachiRana WebMap application, specifically related to its remote scanning feature. The flaw lies within the function nmap_newscan of the file functions_nmap.py, which is integral to executing new Nmap scans. The vulnerability allows for OS command injection through improper handling of the target parameters, enabling an attacker to execute arbitrary commands on the server remotely. This can have severe consequences for organizations that rely on SabyasachiRana WebMap for network mapping and scanning, as it potentially opens up their systems to unauthorized access and exploitation.

The vulnerability poses risks to the integrity and confidentiality of the data processed by the application, and if exploited, it could lead to system compromise. Organizations utilizing the SabyasachiRana WebMap without applying the necessary patches may find themselves vulnerable to exploitation, especially in environments where remote scanning functionalities are critical for operational procedures.

Potential impact of CVE-2026-90843

1. Remote Code Execution: The primary consequence of this vulnerability is the potential for remote code execution (RCE). Attackers could execute arbitrary commands on the host machine, gaining full control over the server where the application is running, leading to unauthorized access to sensitive data.

2. Data Breach and Financial Loss: The exploitation of this vulnerability could result in significant data breaches, exposing sensitive organizational data to malicious actors. Such breaches can lead to financial losses, loss of customer trust, and potential legal ramifications depending on regulatory requirements regarding data protection.

3. Operational Disruption: Organizations affected by successful exploitation of this vulnerability may experience operational disruptions. Compromised systems can lead to downtime, disruption of business processes, and additional costs related to incident response and recovery efforts. This can adversely impact overall productivity and service delivery.
