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: 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 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.

What to do

AI-suggested

To mitigate CVE-2024-46879, organizations should first verify if they are running Tiki CMS version 21.2 and restrict access to the tiki-admin_system.php endpoint to trusted users only. Employing a Web Application Firewall (WAF) with rules targeting reflected XSS payloads can provide an additional layer of defense. Educate users and administrators about the risks of clicking untrusted links or submitting suspicious forms to reduce the likelihood of successful social engineering. Enforce the principle of least privilege to limit the impact of compromised accounts. Monitor logs for unusual POST requests to tiki-admin_system.php and anomalous user activity that may indicate exploitation attempts. Once an official patch or update is released by Tiki CMS maintainers, apply it promptly. Additionally, consider implementing Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context.

Description

CVE-2024-46879 is a reflected Cross-Site Scripting (XSS) vulnerability in the POST parameter zipPath of tiki-admin_system.php in Tiki CMS version 21.2. An attacker can craft malicious JavaScript code that is reflected back to the user, potentially leading to unauthorized actions or access to sensitive information. Exploitation requires the victim to interact with a malicious link or payload, and the attacker must have at least low privileges on the system. The vulnerability impacts confidentiality and integrity but does not affect availability. No public exploits are currently known. The CVSS score is 5.4 (medium severity), reflecting the need for user interaction and limited privileges required. Organizations using Tiki CMS 21.

Impact

The primary impact of CVE-2024-46879 is on the confidentiality and integrity of user sessions within Tiki CMS installations running version 21.2. Successful exploitation allows attackers to execute arbitrary JavaScript code in the victim's browser, potentially leading to session hijacking, theft of sensitive data, or unauthorized actions such as changing settings or accessing restricted content. While availability is not directly affected, the compromise of administrative or privileged user accounts could lead to further attacks or data breaches. Organizations using Tiki CMS for content management, especially those with sensitive or confidential data, face risks of data leakage and unauthorized modifications. The requirement for user interaction and low privileges reduces the ease of exploitation but does not eliminate risk, particularly in environments with many users or where social engineering is feasible. The lack of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a significant threat if weaponized. Failure to address this vulnerability could lead to reputational damage, regulatory non-compliance, and operational disruptions in affected organizations.
