Summary
by MITRE • 07/07/2025
JobCenter through 7e7b0b2 allows account takeover via the password reset feature because SERVER_NAME is not configured and thus a reset depends on the Host HTTP header.

The vulnerability described in CVE-2025-43932 affects JobCenter version 7e7b0b2 and earlier, presenting a critical security flaw in the password reset functionality that could lead to unauthorized account access. This issue stems from improper server configuration where the SERVER_NAME parameter remains unconfigured, creating a dependency on the Host HTTP header for password reset operations. The flaw represents a significant weakness in the application's authentication mechanism and demonstrates poor security practices in web application development.
The technical root cause of this vulnerability lies in the application's reliance on the HTTP Host header for generating password reset URLs without proper validation or configuration of the server name. When SERVER_NAME is not properly configured, the application defaults to using the Host header value directly in the reset URL generation process. This creates a potential attack vector where malicious actors can manipulate the Host header to redirect password reset links to attacker-controlled domains, enabling them to intercept reset tokens and gain unauthorized access to user accounts. The vulnerability falls under CWE-601, which specifically addresses URL redirection and forwarding vulnerabilities where applications fail to validate or properly handle redirect URLs.
The operational impact of this vulnerability extends beyond simple account compromise, as it enables sophisticated attack scenarios that could lead to widespread unauthorized access within the system. An attacker could potentially craft malicious password reset requests that redirect users to phishing domains, allowing for credential theft and session hijacking. The vulnerability also creates opportunities for man-in-the-middle attacks where attackers can intercept and manipulate reset tokens during transmission. This weakness directly impacts the principle of least privilege and authentication integrity, as it undermines the application's ability to properly verify user identities during the reset process.
Security professionals should immediately address this vulnerability by configuring the SERVER_NAME parameter properly within the application's configuration files, ensuring that password reset URLs are generated using a trusted and validated server name rather than relying on potentially manipulated HTTP headers. Additionally, implementing proper input validation for Host headers and using absolute URLs for password reset operations would significantly mitigate this risk. Organizations should also consider implementing additional security controls such as rate limiting for password reset requests and monitoring for unusual patterns in reset activity. This vulnerability aligns with ATT&CK technique T1566, which covers social engineering through phishing and credential theft, as it enables attackers to exploit the reset mechanism to gain unauthorized access to user accounts. The fix should include comprehensive testing to ensure that the password reset functionality properly validates all URL components and that no reliance exists on untrusted HTTP headers for critical security operations.
