CVE-2019-19613 in RAQuest
Summary
by MITRE
** DISPUTED ** An issue was discovered in Halvotec RaQuest 10.23.10801.0. The login page of the admin application is vulnerable to an Open Redirect attack allowing an attacker to redirect a user to a malicious site after authentication. The attacker needs to be on the same network to modify the victim's request on the wire. NOTE: the vendor does not recognize this issue and will not patch it.

The vulnerability identified as CVE-2019-19613 affects Halvotec RaQuest version 10.23.10801.0, specifically targeting the administrative login page implementation. This represents a critical security flaw that enables unauthorized redirection of authenticated users to malicious websites. The vulnerability manifests as an open redirect vulnerability that operates through manipulation of the application's authentication flow, potentially allowing attackers to execute social engineering campaigns or phishing attacks against legitimate users. The issue resides in the application's handling of redirect parameters during the authentication process, where proper validation and sanitization of redirect URLs are absent or insufficient.
The technical implementation of this vulnerability stems from inadequate input validation within the application's authentication mechanism. When users attempt to log into the administrative interface, the system accepts redirect parameters without proper verification of their destination. This allows an attacker positioned within the same network segment to intercept and modify HTTP requests in transit, specifically targeting the redirect URL parameter that is typically used to return users to their intended destination after successful authentication. The vulnerability operates at the application layer and requires network-level access to manipulate traffic, making it a network-based attack vector that aligns with attack techniques described in the mitre att&ck framework under the network infiltration category. This weakness maps directly to common weakness enumeration cwe-601 which specifically addresses open redirect vulnerabilities.
The operational impact of this vulnerability extends beyond simple redirection, as it creates a significant attack surface for malicious actors seeking to compromise user sessions or gather sensitive information. Once authenticated, users who are redirected to malicious sites could be tricked into entering credentials for additional services, or the attacker could exploit the session to perform unauthorized administrative actions. The vulnerability's network proximity requirement limits its scope but does not eliminate the risk, particularly in environments where network segmentation is inadequate or where attackers can establish footholds through other means. The impact is further amplified by the fact that administrators may be more trusting of redirected URLs, potentially leading to successful social engineering attacks that could compromise entire network infrastructures.
Given that the vendor has disputed this vulnerability and refuses to provide a patch, organizations must implement compensating controls to mitigate the risk. Network-level defenses should include implementing strict firewall rules that prevent unauthorized redirection traffic and monitoring for suspicious redirect patterns in network logs. Application-level mitigations involve implementing strict URL validation that only permits redirection to predetermined whitelisted domains or absolute paths within the application itself. Organizations should also consider implementing network segmentation to limit the attack surface and ensure that administrative interfaces are not accessible from untrusted network segments. The absence of vendor support for this vulnerability creates a significant risk management challenge, requiring organizations to develop internal remediation strategies while maintaining awareness of potential exploitation attempts. This scenario exemplifies the importance of proactive security measures and the limitations of relying solely on vendor-provided security updates, particularly when dealing with critical infrastructure applications that may not receive ongoing support or patches.
