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.

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 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

European organizations should immediately audit their Inis installations to identify affected versions (2.0.0 and 2.0.1). In the absence of an official patch, organizations should implement strict input validation and sanitization on the 'p_url' parameter to restrict requests to trusted domains or internal endpoints. Network-level controls such as egress filtering and segmentation should be enforced to limit the server's ability to make arbitrary outbound requests. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious SSRF patterns can provide additional protection. Monitoring server logs for unusual outbound requests originating from the vulnerable endpoint can help detect exploitation attempts early. Privilege management should be reviewed to minimize the number of users or processes with the required privileges to exploit this vulnerability. Finally, organizations should stay alert for official patches or updates from Inis and apply them promptly once available.

Description

A vulnerability was found in Inis up to 2.0.1. It has been rated as critical. This issue affects some unknown processing of the file app/api/controller/default/Proxy.php. The manipulation of the argument p_url leads to server-side request forgery. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-249875.

Impact

For European organizations using Inis versions 2.0.0 or 2.0.1, this SSRF vulnerability could lead to unauthorized internal network access, data leakage, or disruption of services. Given the ability to manipulate server requests, attackers might exploit this flaw to reach internal APIs, databases, or cloud metadata endpoints, potentially exposing sensitive information or enabling further attacks. Critical infrastructure, financial institutions, and government agencies in Europe that rely on Inis for internal or external services could face confidentiality breaches or service interruptions. The medium severity rating suggests that while the vulnerability is not trivially exploitable by unauthenticated attackers, the requirement for some privileges limits the attack surface somewhat. However, once exploited, the attacker could escalate their access or move laterally within the network, increasing the overall risk. The public disclosure of the vulnerability also raises the urgency for European organizations to assess their exposure and implement mitigations promptly to avoid targeted attacks.

Summary

CVE-2024-0308 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Inis software versions up to 2.0.1. The vulnerability arises from improper handling of the 'p_url' parameter in the file app/api/controller/default/Proxy.php. An attacker can manipulate this parameter to coerce the server into making unintended HTTP requests to arbitrary locations. SSRF vulnerabilities enable attackers to bypass network access controls, potentially accessing internal systems, sensitive data, or services that are otherwise inaccessible externally. The vulnerability is remotely exploitable without user interaction but requires some level of privileges (PR:L) on the system, as indicated by the CVSS vector. The CVSS score of 6.3 (medium severity) reflects the moderate impact on confidentiality, integrity, and availability, with low attack complexity and no user interaction needed. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The lack of available patches at the time of disclosure means that affected organizations must rely on mitigation strategies until official fixes are released. SSRF vulnerabilities like this can be leveraged to perform internal reconnaissance, access metadata services, or pivot to other internal resources, posing significant risks especially in cloud or segmented network environments.
