CVE-2022-25799 in VINCE
Summary
by MITRE • 08/17/2022
An open redirect vulnerability exists in CERT/CC VINCE software prior to 1.5.0. An attacker could send a link that has a specially crafted URL and convince the user to click the link. When an authenticated user clicks the link, the authenticated user's browser could be redirected to a malicious site that is designed to impersonate a legitimate website. The attacker could trick the user and potentially acquire sensitive information such as the user's credentials.

The CVE-2022-25799 vulnerability represents a critical open redirect flaw within the CERT/CC VINCE software platform, affecting versions prior to 1.5.0. This vulnerability stems from inadequate input validation and sanitization of redirect parameters within the application's URL handling mechanisms. The flaw allows malicious actors to construct specially crafted URLs that, when clicked by authenticated users, trigger unintended redirection to attacker-controlled domains. The vulnerability falls under the CWE-601 category of URL Redirection to Untrusted Site, which is classified as a serious security weakness in web application development practices.
The technical implementation of this vulnerability exploits the software's failure to properly validate and sanitize redirect URLs before executing the redirection process. When an authenticated user interacts with a maliciously crafted link, the application processes the redirect parameter without sufficient validation, allowing the attacker to specify arbitrary destination URLs. This creates a dangerous attack surface where users are tricked into believing they are navigating to legitimate CERT/CC VINCE pages while actually being redirected to phishing sites designed to harvest credentials and other sensitive information. The vulnerability specifically targets the authentication context of the application, making authenticated sessions particularly susceptible to exploitation.
The operational impact of this vulnerability extends beyond simple phishing attacks, as it can be leveraged for sophisticated social engineering campaigns. Attackers can craft convincing redirect links that appear legitimate within the context of the VINCE platform, making user detection of malicious intent significantly more difficult. The vulnerability is particularly dangerous in environments where users frequently access the platform with elevated privileges, as successful exploitation could lead to complete account compromise and potential lateral movement within the organization's security infrastructure. This represents a significant risk to the integrity of the CERT/CC VINCE platform and the sensitive information it manages.
Mitigation strategies for CVE-2022-25799 should focus on implementing proper input validation and URL sanitization mechanisms within the application's redirect handling code. Organizations should immediately upgrade to VINCE version 1.5.0 or later, which includes patches addressing this vulnerability. Additionally, implementing strict whitelist validation for redirect URLs, employing secure coding practices for URL parameter handling, and conducting regular security assessments of web application components can help prevent similar vulnerabilities. The ATT&CK framework categorizes this vulnerability under T1566 - Phishing, with specific techniques including T1566.001 - Spearphishing Attachment and T1566.002 - Spearphishing Link, highlighting the importance of network-level monitoring and user education initiatives to detect and prevent exploitation attempts.
