Bug Bounty Report - Mozilla Firefox Certificate Vulnerability


Summary:

I have discovered a vulnerability in the Mozilla Firefox browser's "about:certificate?cert=[data]" feature that can potentially lead to malicious exploitation. This vulnerability allows an attacker to create a scenario where a victim is encouraged to click on a link within the certificate details, leading to unintended and potentially harmful actions.


Vulnerability Details:

The vulnerability lies in the "about:certificate?cert=[data]" feature of Mozilla Firefox, which displays SSL certificate information. By manipulating the "data" parameter, an attacker can craft a scenario where a clickable link is presented to the victim in the "Organisation" field of the certificate details.


Impact:

This vulnerability can have severe consequences, as it can trick users into clicking on a malicious link that appears to be from a reputable source. Victims may be more likely to trust the link as it is displayed within the browser's SSL certificate view. The attack is difficult to detect by conventional antivirus solutions, making it a potent vector for social engineering attacks and potentially leading to unauthorized data access, phishing, or malware installation.


Reproduction Steps:


Open Mozilla Firefox browser.

Type "about:certificate?cert=[data]" in the address bar and press Enter.

Observe the SSL certificate details page.

Craft the malicious scenario: Create a clickable link in the "Organisation" field that appears legitimate but leads to a malicious target.

Encourage the victim to view the certificate using the provided link.

Affected Components:

The vulnerability affects the SSL certificate view feature of Mozilla Firefox, specifically the way it displays certificate information and allows manipulation of the "data" parameter.


Technical Evidence:

I have prepared a proof of concept that demonstrates the vulnerability by crafting a scenario where a malicious link is embedded within the "Organisation" field of the SSL certificate details page. Screenshots and code snippets are available upon request.


Recommendation:

To mitigate this vulnerability, I recommend that Mozilla Firefox developers implement proper input validation and sanitization for the "about:certificate?cert=[data]" feature. Additionally, considering the potential severity of the impact, it might be prudent to reconsider generating the "data" parameter in the URL for this purpose.


CVE (Common Vulnerabilities and Exposures):

I suggest assigning a CVE ID to this vulnerability for tracking purposes. CVE-XXXX-XXXXX

Additional research and background information related to this vulnerability are available upon request.
