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.

AI-suggested

To mitigate CVE-2024-39143, organizations should prioritize upgrading ResidenceCMS to a patched version once available. In the absence of official patches, implement strict input validation to disallow or sanitize HTML tags and scripts in property content fields. Employ robust output encoding (e.g., HTML entity encoding) when rendering user-generated content to prevent script execution. Use Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce XSS impact. Conduct regular security audits and penetration testing focused on input handling. Limit user privileges to the minimum necessary and monitor logs for suspicious content submissions. Educate users about the risks of clicking untrusted links within the CMS. Additionally, consider deploying web application firewalls (WAFs) with XSS detection rules tailored to ResidenceCMS traffic patterns. These combined measures reduce the likelihood and impact of exploitation.

Description

A stored cross-site scripting (XSS) vulnerability exists in ResidenceCMS 2.10.1 that allows a low-privilege user to create malicious property content with HTML inside which acts as a stored XSS payload.

Impact

The primary impact of CVE-2024-39143 is the potential compromise of user confidentiality and integrity within ResidenceCMS environments. Attackers can steal session cookies or authentication tokens, enabling account takeover or privilege escalation. They may also perform unauthorized actions on behalf of victims, such as modifying content or accessing sensitive data. While availability is not affected, the reputational damage and data leakage risks are significant for organizations managing real estate listings or property management portals. Since the vulnerability requires user interaction, social engineering or phishing may be used to lure victims to malicious property pages. Organizations worldwide using ResidenceCMS 2.10.1, especially those with many users or sensitive data, face increased risk of targeted attacks. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a credible threat if weaponized.

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.
