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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
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.

Exploitation evidence

Disclosed: evidence found.
CVE published 30 Apr 2024
Detectable: evidence found.
nuclei template: OneNav v0.9.35-20240318 - Server-Side Request Forgery (SSRF)
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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

To mitigate CVE-2024-33832, organizations should first apply any available patches or updates from the OneNav vendor once released. In the absence of patches, implement strict input validation and sanitization on the /index.php?c=api&method=get_link_info endpoint to ensure only authorized and safe URLs can be requested. Employ allowlisting of outbound HTTP requests from the server to restrict connections to trusted domains and IP ranges, effectively preventing SSRF exploitation. Network segmentation should be enforced to limit the server's ability to reach sensitive internal services. Monitoring and logging of outbound requests can help detect anomalous activity indicative of SSRF attempts. Additionally, review and minimize user privileges to reduce the risk posed by attackers with limited access. Employ web application firewalls (WAFs) with SSRF detection capabilities to block suspicious requests. Regular security assessments and penetration testing focused on SSRF vectors can help identify and remediate weaknesses proactively.

Description

OneNav v0.9.35-20240318 was discovered to contain a Server-Side Request Forgery (SSRF) via the component /index.php?c=api&method=get_link_info.

Impact

The impact of CVE-2024-33832 is significant for organizations running vulnerable versions of OneNav, as SSRF vulnerabilities can lead to unauthorized access to internal systems, data leakage, and potential lateral movement within networks. Confidentiality may be compromised if attackers retrieve sensitive internal information or metadata. Integrity could be affected if attackers manipulate internal services or APIs through forged requests. Availability might be impacted if attackers use the SSRF to launch denial-of-service attacks against internal resources. Since the vulnerability requires some level of privilege, the risk is somewhat mitigated but still notable, especially in environments where user privileges are not tightly controlled. Organizations with OneNav deployments in critical infrastructure, government, or enterprise environments face increased risk due to the potential for internal network compromise and data exfiltration. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability is public.
