Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2014-2120 is a cross-site scripting vulnerability, tracked as Bug ID CSCun19025 and assigned CWE-79, that affects the WebVPN login page in Cisco Adaptive Security Appliance (ASA) Software. The flaw permits injection of arbitrary web script or HTML through an unspecified parameter on the login page.
Remote attackers can exploit the issue over the network without authentication by crafting a malicious request that triggers script execution in a victim's browser when the user interacts with the WebVPN login page. Successful exploitation yields limited impacts to confidentiality and integrity, with changed scope due to the reflected or stored script running in the context of the affected Cisco ASA interface.
Advisories referenced at the Cisco Security Notice URL and related trackers such as SecurityFocus and SecurityTracker provide further details on the affected releases and recommended actions. No information on observed real-world exploitation is included in the supplied data.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
