CVE-2024-50339 is a critical-severity Cross-site Scripting (CWE-79) vulnerability in Glpi-Project Glpi. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked in the top 3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-3 (Device Identification and Authentication) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
GLPI, an open-source IT asset and service management application, contains a session management flaw in versions 9.5.0 through 10.0.16. An unauthenticated remote attacker can enumerate all active session identifiers, enabling the theft of any valid user session. The issue is tracked under CWE-287 and CWE-384 and carries a CVSS 4.0 score of 9.3.
Because the attack requires no credentials or user interaction, an adversary can obtain full access to any authenticated session, including those belonging to administrators. Successful exploitation grants the ability to view, modify, or delete arbitrary data within the GLPI instance and potentially pivot further into connected systems.
The project’s security advisory and the 10.0.17 release notes state that the vulnerability is resolved by updating to version 10.0.17 or later. The current EPSS score of 0.1976, with a recorded peak of 0.2196, indicates moderate and relatively stable exploitation interest since disclosure.

Vulnerability Data
GLPI is a free asset and IT management software package. Starting in version 9.5.0 and prior to version 10.0.17, an unauthenticated user can retrieve all the sessions IDs and use them to steal any valid session. Version 10.0.17 contains a…

Mitigating Controls (NIST 800-53 r5) AI
Mandates unique identification and authentication of organizational users before access, directly stopping improper authentication.
Requires unique identification and authentication of devices before establishing connections, preventing unauthenticated device claims.
Mandates unique identification and authentication of non-organizational users, directly addressing the weakness for external actors.
Manages authenticators with verification and secure distribution, reducing opportunities for improper authentication.
Developer testing and evaluation can discover missing or incorrect input neutralization through targeted web-application tests.
Requires protection of session authenticity, which directly stops an attacker from using a stolen or fixed session identifier after authentication.

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.
PR.AA-03 directly enforces authentication mechanisms that eliminate most improper-authentication defects, yet CWE-287 spans additional vectors (missing checks, flawed protocols, session handling) that one control does not fully close.
PR.AA-04 directly enables verification of identity assertions (mostly preventing CWE-287 in that scope) yet leaves many other authentication failure modes unaddressed (only partial prevention overall).
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).
PR.AA-01 supplies and governs credentials/tokens that authentication relies on, removing some weak-credential cases, yet leaves verification logic, missing checks, and protocol flaws untouched.
PR.AA-02 ensures valid enrollment and unique credential binding, which reduces some improper-auth risks at issuance time but leaves runtime claim verification untouched, so each direction only partially addresses the other.
PR.PS-01 can enforce auth-related settings via hardened baselines and default reviews, blocking some config-based instances of CWE-287, yet leaves code-level auth flaws untouched so neither direction reaches mostly.

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.
Requiring authentication methods whose strength matches the sensitivity of the data and mandating multi-factor authentication directly blocks attempts to access resources without proving identity.
Verifying user identity before issuing replacement credentials and forcing changes after compromise reduces the likelihood that authentication bypass can be achieved through stolen or weak credentials.
Secure-coding testing and automated code-analysis tools are applied to detect improper neutralization of script-related content during web-page generation.
Access-control policy can mandate session invalidation on re-authentication, but does not prescribe the technical mechanism.
Mandating segregated approval and oversight for non-human identities reduces the chance that weak or orphaned credentials can be exploited for unauthorized authentication.
Knowledge exchange on emerging attack techniques and patches reduces the likelihood that cross-site scripting flaws remain unaddressed in deployed applications.
