User Interaction: Required

Bold values are the worst case: easiest to exploit or largest impact.

Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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).
Availability: None: There is no impact to availability within the impacted component.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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.
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.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.

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 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 prioritize upgrading the Archer Platform to version 2024.08 or later, where this vulnerability is addressed. If you cannot patch yet, implement strict input validation and output encoding on all user-supplied data reflected in the Dashboard Listing page to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context. Educate users to be cautious of unsolicited links or inputs, especially those received via email or messaging platforms. Monitor web application logs for unusual URL parameters or suspicious input patterns that may indicate attempted exploitation. Consider deploying Web Application Firewalls (WAFs) with rules designed to detect and block reflected XSS payloads targeting the Archer Platform. Regularly review and update security policies and incident response plans to handle potential XSS incidents. Coordinate with the vendor for timely updates and advisories related to this vulnerability.

Description

Reflected XSS was discovered in a Dashboard Listing Archer Platform UX page in Archer Platform 6.x before version 2024.08. A remote unauthenticated attacker could potentially exploit this by tricking a victim application user into supplying malicious HTML or JavaScript code to the vulnerable web application; the malicious code is then reflected back to the victim and executed by the web browser in the context of the vulnerable web application.

Impact

The primary impact of CVE-2024-49211 is on confidentiality, as attackers can execute malicious scripts in the context of a victim’s browser session, potentially stealing sensitive information such as session cookies, authentication tokens, or other private data accessible through the Archer Platform interface. This can lead to unauthorized access to the victim’s account or sensitive organizational data. The integrity impact is low but present, as attackers might perform limited unauthorized actions on behalf of the victim if the platform does not implement additional safeguards like CSRF tokens or action confirmations. Availability is not affected by this vulnerability. Since the vulnerability is exploitable remotely without authentication but requires user interaction, the attack vector relies on social engineering or phishing campaigns targeting users of the Archer Platform. Organizations using affected versions face risks of data breaches, loss of user trust, and potential compliance violations if sensitive data is exposed. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits rapidly after public disclosure.

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.
