Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.
Exploit Code Maturity: Functional: Functional exploit code is available. The code works in most situations where the vulnerability exists.
Remediation Level: Temporary Fix: There is an official but temporary fix available. This includes instances where the vendor issues a temporary hotfix, tool, or workaround.
Report Confidence: Confirmed: Detailed reports exist, or functional reproduction is possible (functional exploits may provide this). Source code is available to independently verify the assertions of the research, or the author or vendor of the affected code has confirmed the presence of the vulnerability.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Organizations should immediately verify if they are running affected versions of FortiAnalyzer or FortiAnalyzer-BigData and apply vendor-provided patches or updates as soon as they become available. Until patches are applied, restrict administrative access to these systems using network segmentation, VPNs, and strict firewall rules to limit exposure. Enforce strong authentication mechanisms, including multi-factor authentication, to reduce the risk of credential compromise. Regularly audit user accounts and privileges to ensure only necessary personnel have high-level access. Monitor logs for unusual or unauthorized activity that could indicate exploitation attempts. Implement web application firewalls (WAFs) or intrusion detection/prevention systems (IDS/IPS) with rules tuned to detect SQL injection patterns targeting FortiAnalyzer interfaces. Educate administrators on the risks of SQL injection and the importance of secure coding and input validation practices. Finally, maintain an incident response plan that includes procedures for handling potential exploitation of this vulnerability.

Description

CVE-2025-49784 is a medium severity SQL injection vulnerability affecting multiple versions of Fortinet FortiAnalyzer and FortiAnalyzer-BigData products. It allows an authenticated attacker with high privileges to execute unauthorized code or commands by sending specially crafted requests. The vulnerability impacts FortiAnalyzer versions 6.2 through 7.6.4 and FortiAnalyzer-BigData versions 6.2 through 7.6.0. Exploitation requires no user interaction but does require authentication with elevated privileges.

Impact

The vulnerability allows an authenticated attacker with high privileges to execute unauthorized commands or code, potentially leading to unauthorized data access or manipulation. This can compromise the confidentiality of sensitive security logs and analytics data, which may contain critical information about network security posture and incidents. Integrity impact is limited but could allow attackers to alter logs or configurations, undermining trust in security monitoring. Availability impact is also limited but could result in partial service disruption or degraded performance. Organizations relying on FortiAnalyzer and FortiAnalyzer-BigData for centralized security event management could face increased risk of insider threats or lateral movement by attackers who gain privileged access. The medium severity rating reflects the requirement for authenticated access and the limited scope of impact, but the critical role of these products in security infrastructure elevates the overall risk. The absence of known exploits in the wild reduces immediate threat but does not eliminate the risk of future exploitation.
