Exploitation Conditions

Exploitation requires local access (AV:L) to a system running the FortiDLP agent and at least low privileges (PR:L) sufficient to read the agent's log files, where the enrollment code has been improperly logged (CWE-532). The core prerequisite is that a valid enrollment code is present in a readable log and can be re-used. Limiting factors: the attacker must already be on the host with some privilege, no remote unauthenticated path is indicated by the CVSS vector, and impact is limited to partial information disclosure (C:L/I:L, A:N). This substantially constrains real-world risk relative to a remotely exploitable flaw.

Impact

This is a low-to-moderate priority issue despite being a Fortinet product. The CVSS base score of 4.4 (Medium) is driven by a local attack vector (AV:L), low attack complexity (AC:L), and required privileges (PR:L), yielding only Low confidentiality and integrity impact (C:L/I:L) and no availability impact. The signals are mutually consistent and point AWAY from widespread risk: EPSS is 0.16% (4th percentile), there is no CISA KEV listing, and no public exploit code was identified. The vulnerability (CWE-532, sensitive information in a log file, exploitable by re-using an enrollment code) is an information-disclosure weakness that requires existing local access and some privilege level, not a remotely weaponizable flaw. No SSVC decision data was provided in the input. There is one point worth verifying: the CVSS vector specifies a LOCAL attack vector (AV:L), yet 're-using the enrollment code' could in some deployments imply a network-adjacent or enrollment-service interaction - the vendor advisory (FG-IR-25-160) should be consulted to confirm whether the enrollment code is consumed locally (e.g., written to a readable log) or exchanged over a network path. Treat this as routine-patch priority, not emergency.

Exploit ScenarioDerived

An attacker with local, low-privilege access to a host running the FortiDLP agent reads agent log files where the enrollment code has been improperly recorded, then re-uses that captured enrollment code to disclose sensitive information. No public exploit code was identified at time of analysis, so exploitation would require manual effort against a specific installation.

AnalysisAIv1 – Oct 09, 2026

Information disclosure in FortiDLP Agent 12.0.0 through 12.0.5, 11.5.1, 11.4.6, and 11.4.5 allows local users with low privileges to read enrollment codes improperly written to log files and reuse them, causing limited confidentiality and integrity impact. Exploitation requires local access and readable logs; no public exploit identified at time of analysis, and EPSS is low at 0.16% (4th percentile). Fortinet advisory FG-IR-25-160 is available, and this is a low-to-moderate priority issue despite being a Fortinet product.

RemediationAI

Consult and apply the fixed version specified in Fortinet's advisory FG-IR-25-160 (https://fortiguard.fortinet.com/psirt/FG-IR-25-160); the provided data does not give an exact patched version, so do not assume that simply running any 12.0.x build is fixed. Until patched, restrict filesystem permissions on FortiDLP agent log files so only required administrator/service accounts can read them, and enable log redaction or suppress enrollment-code logging where the product allows it; this reduces exposure but may impair troubleshooting and forensic detail. If an enrollment code is suspected of being logged, revoke and reissue it, then re-enroll affected agents, accepting possible disruption to legitimate enrollment; also monitor for unexpected agent enrollments or reuse of the code. These compensating controls target the local log-read prerequisite and the code-reuse path rather than a remote attack vector.

Technical ContextAI · show details

FortiDLP Agent is the endpoint component identified by CPE cpe:2.3:a:fortinet:fortidlp_agent:*:*:*:*:*:*:*:*; affected releases are 12.0.0 through 12.0.5, 11.5.1, 11.4.6, and 11.4.5. The flaw is CWE-532 Insertion of Sensitive Information into Log File: the agent writes the enrollment code into a log file, and a local user with low privileges (CVSS PR:L) can read that file and reuse the code. The CVSS vector AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N confirms local access, low privileges, no user interaction, and limited confidentiality and integrity impact with no availability impact. Reusing the enrollment code may allow an attacker to enroll or influence agent state, but the assessment does not indicate a remote unauthenticated vector.
