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: 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 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-2024-48120, organizations should first monitor X2CRM vendor communications for official patches or updates addressing this vulnerability and apply them promptly. In the absence of patches, implement strict input validation and sanitization on the 'Name' field within the Opportunities module to prevent malicious script injection. Employ output encoding techniques to ensure any user-supplied data rendered in the UI is safely escaped. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context. Limit user privileges to the minimum necessary to reduce the risk of exploitation by low-privilege attackers. Conduct regular security awareness training to help users recognize suspicious behavior or unexpected UI elements. Additionally, consider implementing web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting the CRM application. Regularly audit and monitor application logs for unusual activity that may indicate attempted exploitation.

Description

X2CRM v8.5 is vulnerable to a stored Cross-Site Scripting (XSS) in the "Opportunities" module. An attacker can inject malicious JavaScript code into the "Name" field when creating a list.

Impact

The stored XSS vulnerability in X2CRM can have several impacts on organizations worldwide. Attackers can exploit this flaw to execute arbitrary JavaScript in the context of authenticated users, leading to session hijacking, credential theft, or unauthorized actions within the CRM system. This can compromise sensitive customer data, disrupt business operations, and damage organizational reputation. The vulnerability affects confidentiality by exposing sensitive information, integrity by allowing unauthorized actions or data manipulation, and availability if attackers use the exploit to perform denial-of-service attacks or disrupt workflows. Since the vulnerability requires some level of authentication and user interaction, the attack surface is somewhat limited but still significant in environments with multiple users and collaborative workflows. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability becomes widely known.
