Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-10 requires validating and sanitizing inputs to the article category title field to block crafted XSS payloads.

prevent

SI-15 mandates output filtering and encoding of title field content when rendered in web pages to prevent script execution.

prevent

SI-2 ensures timely patching or remediation of the specific XSS flaw in Emlog Pro v2.5.4.

MITRE ATT&CK Enterprise TechniquesAI

T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
T1185 Browser Session Hijacking Collection
Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
Why these techniques?

Stored XSS enables arbitrary JavaScript execution in victim browsers (T1059.007), directly facilitating browser session hijacking (T1185) and theft of web session cookies (T1539) via injected payloads in the Title field.

Deeper analysisAI

CVE-2025-25825 is a cross-site scripting (XSS) vulnerability, classified under CWE-79, affecting Emlog Pro version 2.5.4. The flaw allows attackers to execute arbitrary web scripts or HTML by injecting a crafted payload into the Title field within the article category section. Published on 2025-02-26, it has a CVSS v3.1 base score of 7.1, reflecting high confidentiality and integrity impacts with no availability impact.

The vulnerability can be exploited by attackers requiring local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R), with unchanged scope (S:U). Exploitation involves crafting and injecting a malicious payload into the specified Title field, enabling execution of scripts in the context of affected users' browsers, potentially leading to theft of sensitive data or manipulation of page content.
