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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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.

Exploitation evidence

Disclosed: evidence found.
CVE published 11 Nov 2024
Detectable: no evidence on record.
No public nuclei template indexed
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 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

Organizations should immediately verify their Axigen Mail Server version and upgrade to the patched releases 10.3.3.67, 10.4.42, or 10.5.29 as applicable. In addition to patching, administrators should implement strict input validation and output encoding on all user-controllable fields, especially cookies and URL parameters, to prevent injection of malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the mail server. Educate users about the risks of clicking unknown links or opening suspicious emails to reduce the likelihood of user interaction exploitation. Monitor web server logs for unusual requests targeting the themeMode cookie or _h parameter and consider deploying web application firewalls (WAFs) with custom rules to detect and block XSS payloads. Regularly audit and test the mail server environment for similar vulnerabilities and maintain an incident response plan to quickly address any exploitation attempts. Finally, review session management practices to limit session lifetime and scope to reduce the impact of session hijacking.

Description

Persistent and reflected XSS vulnerabilities in the themeMode cookie and _h URL parameter of Axigen Mail Server up to version 10.5.28 allow attackers to execute arbitrary Javascript. Exploitation could lead to session hijacking, data leakage, and further exploitation via a multi-stage attack. Fixed in versions 10.3.3.67, 10.4.42, and 10.5.29.

Impact

The primary impact of CVE-2024-50601 is the compromise of user sessions and confidentiality within organizations using vulnerable Axigen Mail Server versions. Attackers can hijack sessions, leading to unauthorized access to sensitive email communications and potentially internal systems if session tokens are reused or provide access to other resources. Data leakage risks include exposure of sensitive emails or credentials stored or accessible via the mail server interface. The vulnerability also opens the door for multi-stage attacks, where initial XSS exploitation can be leveraged to deploy malware, conduct phishing, or escalate privileges. Organizations relying on Axigen Mail Server for critical email infrastructure face risks of operational disruption and reputational damage if exploited. Since exploitation requires user interaction, phishing campaigns or social engineering could be used to trigger the vulnerability. The medium severity indicates a moderate but non-trivial risk, especially in environments with high-value targets or lax user security awareness.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
