Arachnys Cabot 0.11.12 is vulnerable to stored cross-site scripting (XSS) through the Address column, enabling potential account takeover.
Vulnerability
Analysis
CVE-2020-25449 is a stored cross-site scripting (XSS) vulnerability found in Arachnys Cabot version 0.11.12. The flaw exists because user-supplied input in the Address column is not properly sanitized before being stored and later rendered by the application [1][4]. This is a classic example of insufficient input validation in a web application.
Exploitation
Vector
An attacker can exploit this vulnerability by first creating a user account (or using an existing one with sufficient privileges) and navigating to the instance creation page at /instance/create/. There, they can inject a malicious payload, such as ``, into the Address column. The payload is stored and executed when an administrator views the affected instance or receives a notification [4]. The attack leverages a blind XSS technique, meaning the payload fires in the background without the victim's immediate awareness.
Impact
The primary impact is that an attacker can steal session cookies, capture screenshots, and exfiltrate sensitive data of the admin account viewing the malicious notification. This can lead to a full administrative account takeover, compromising the monitoring platform's configuration, alerts, and access to underlying infrastructure [4].
Mitigation
Status
As of the advisory, the vendor (Arachnys) had not released a patch for Cabot before its maintenance status became indefinite [2]. Users are advised to upgrade to a newer version if available, or apply manual input sanitization and output encoding as a workaround. The vulnerability has been published in the Exploit Database [4] and tracked in the PyPA advisory database [3].
