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.

Exploitation evidence

Disclosed: evidence found.
CVE published 13 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

To mitigate CVE-2024-45879, organizations should immediately upgrade the TOPqw Webportal to version 1.35.291 or later, where the vulnerability has been fixed. In addition to patching, implement strict input validation and output encoding on all user-supplied data, especially in file upload components and dynamic web content areas, to prevent injection of malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the web application context. Conduct regular security assessments and code reviews focusing on XSS vulnerabilities, particularly in modules handling file uploads and user-generated content. Limit user privileges to the minimum necessary to reduce the risk posed by authenticated attackers. Monitor application logs for suspicious activities indicative of XSS exploitation attempts. Educate users about the risks of interacting with untrusted content within the application. Finally, consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting the TOPqw Webportal.

Description

The file upload function in the "QWKalkulation" tool of baltic-it TOPqw Webportal v1.35.287.1 (fixed in version 1.35.291), in /Apps/TOPqw/QWKalkulation/QWKalkulation.aspx, is vulnerable to Cross-Site Scripting (XSS). To exploit the persistent XSS vulnerability, an attacker has to be authenticated to the application that uses the "TOPqw Webportal" as a software. When authenticated, the attacker can persistently place the malicious JavaScript code in the "QWKalkulation" menu.'

Impact

The primary impact of CVE-2024-45879 is on the confidentiality and integrity of user data within the TOPqw Webportal environment. An attacker exploiting this vulnerability can execute persistent malicious scripts that may steal session tokens, manipulate displayed content, or perform unauthorized actions on behalf of other authenticated users. This can lead to unauthorized access to sensitive information, data leakage, and potential compromise of user accounts. Although availability is not directly affected, the trustworthiness of the application is undermined, which can result in reputational damage and operational disruptions. Organizations relying on the affected version of the TOPqw Webportal, especially those in sectors handling sensitive or regulated data, face increased risk of targeted attacks leveraging this vulnerability. The requirement for attacker authentication and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate the threat in environments with multiple users or insider threats.

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.
