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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: None: There is no impact to availability within 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 2026-10-26.

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.

What to do

AI-suggested

To mitigate CVE-2024-50859, organizations should implement strict input validation and sanitization on the ip_import_acl_csv upload functionality to ensure that any CSV content is properly escaped or encoded before being reflected in HTML responses. Employing Content Security Policy (CSP) headers can help reduce the impact of XSS by restricting script execution sources. Additionally, restricting file upload permissions to only trusted users and monitoring upload activity can reduce exposure. Applying the principle of least privilege to GestioIP user roles minimizes the risk posed by high privilege requirements. Organizations should also monitor vendor communications for patches or updates addressing this vulnerability and apply them promptly once available. In the interim, educating users about the risks of uploading untrusted files and implementing web application firewalls (WAFs) with XSS detection rules can provide additional layers of defense.

Description

The ip_import_acl_csv request in GestioIP v3.5.7 is vulnerable to Reflected XSS. When a user uploads an improperly formatted file, the content may be reflected in the HTML response, allowing the attacker to execute malicious scripts or exfiltrate data.

Impact

The primary impact of CVE-2024-50859 is on the confidentiality and integrity of data within organizations using GestioIP 3.5.7. Successful exploitation could allow attackers to execute arbitrary scripts in the context of authenticated users, potentially leading to session hijacking, unauthorized data access, or manipulation of IP address management data. While availability is not affected, the breach of confidentiality and integrity could compromise network management operations and trust in the system. Since the vulnerability requires authenticated access and user interaction, the attack surface is somewhat limited but still significant in environments where multiple users have access to GestioIP. Organizations managing critical network infrastructure or sensitive IP data could face operational disruptions or data leakage. The absence of known exploits reduces immediate risk, but the vulnerability should be addressed promptly to prevent future exploitation.
