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.

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 2026-10-25.

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-2025-63879, organizations should implement strict input validation and output encoding on the 'id' parameter in the /ecommerce/products.php component. Employ context-aware encoding (e.g., HTML entity encoding) to neutralize malicious scripts before rendering user input. Use Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Educate users and employees about phishing and social engineering tactics to reduce the likelihood of clicking malicious links. Monitor web application logs for suspicious URL patterns and consider deploying Web Application Firewalls (WAFs) with rules targeting reflected XSS payloads. If possible, update or patch the e-commerce platform once a fix is available. In the interim, consider disabling or restricting the vulnerable parameter if feasible. Regular security testing and code reviews should be conducted to identify and remediate similar vulnerabilities.

Description

CVE-2025-63879 is a reflected cross-site scripting (XSS) vulnerability found in the /ecommerce/products.php component of E-commerce Project v1.0 and earlier. Attackers can inject malicious JavaScript code via the 'id' parameter, which executes in the context of a user's browser when they visit a crafted URL. This vulnerability requires user interaction, such as clicking a malicious link, and does not require authentication. The CVSS score is 6.1 (medium severity), reflecting limited impact on confidentiality and integrity but no impact on availability. Although no known exploits are currently in the wild, the vulnerability poses a risk of session hijacking, credential theft, or other client-side attacks. European organizations using this e-commerce platform should prioritize patching or mitigating this issue to protect their customers. Countries with significant e-commerce activity and adoption of this platform are at higher risk.

Impact

For European organizations, this vulnerability can lead to client-side attacks such as session hijacking, credential theft, or unauthorized actions performed in the context of a logged-in user. This can damage customer trust, lead to data breaches, and potentially cause financial losses. Since the vulnerability is reflected XSS, it requires tricking users into clicking malicious links, which can be distributed via phishing emails or social engineering. The impact is particularly significant for e-commerce businesses that handle sensitive customer information and payment details. Additionally, regulatory frameworks like GDPR impose strict requirements on protecting user data, so exploitation could result in legal and compliance repercussions. The lack of availability impact means service disruption is unlikely, but confidentiality and integrity risks remain notable.

Summary

CVE-2025-63879 identifies a reflected cross-site scripting (XSS) vulnerability in the /ecommerce/products.php component of the E-commerce Project version 1.0 and earlier. The vulnerability arises because the 'id' parameter in the URL is not properly sanitized or encoded before being reflected back in the webpage output. This allows an attacker to craft a malicious URL containing JavaScript code embedded in the 'id' parameter. When a user clicks this URL, the injected script executes in their browser under the domain of the vulnerable e-commerce site. This can lead to theft of session cookies, redirection to malicious sites, or execution of arbitrary scripts that compromise user data or perform actions on behalf of the user. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. The CVSS v3.1 vector indicates the attack is network exploitable (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), and there is no impact on availability (A:N). No patches or known exploits are currently reported, but the vulnerability is publicly disclosed as of November 19, 2025.
