CVE-2007-2907 in SSL-Explorer
Summary
by MITRE
Unspecified vulnerability in SSL-Explorer before 0.2.13 allows remote authenticated users to enter redirect URLs containing (1) JavaScript or (2) HTTP headers via an unspecified vector, possibly the forwardTo parameter to redirect.do. NOTE: the impact might be cross-site scripting (XSS) or HTTP request smuggling.

The vulnerability identified as CVE-2007-2907 affects SSL-Explorer software versions prior to 0.2.13 and represents a critical security flaw that enables remote authenticated attackers to manipulate redirect functionality. This issue stems from inadequate input validation within the application's redirect mechanism, specifically involving the forwardTo parameter in the redirect.do endpoint. The vulnerability exists in the context of web application security where proper sanitization of user-supplied data is essential to prevent malicious code execution. The unspecified nature of the exact vector suggests that the flaw may manifest through multiple pathways within the application's redirect handling logic.
The technical implementation of this vulnerability allows authenticated users to inject malicious content into redirect URLs through the forwardTo parameter, creating potential attack vectors for both cross-site scripting and HTTP request smuggling. When the application processes these malformed redirect URLs, it fails to properly validate or sanitize the input before using it in subsequent HTTP responses or redirects. This processing flaw directly maps to CWE-79, which describes cross-site scripting vulnerabilities, and CWE-113, which addresses HTTP response splitting. The vulnerability demonstrates a classic input validation failure where user-controllable data enters the application without proper sanitization, creating opportunities for attackers to manipulate the application's behavior.
The operational impact of this vulnerability extends beyond simple XSS exploitation, as it can potentially enable HTTP request smuggling attacks that may allow attackers to bypass security controls or access restricted resources. An authenticated attacker with access to the SSL-Explorer application can leverage this vulnerability to inject JavaScript code that executes in the context of other users' browsers, potentially leading to session hijacking, credential theft, or data exfiltration. The HTTP header injection capability could also permit attackers to manipulate HTTP responses, potentially enabling them to perform actions such as cache poisoning or bypassing authentication mechanisms. This vulnerability particularly affects web applications that rely on redirect mechanisms for user navigation or authentication flows.
Mitigation strategies for CVE-2007-2907 should focus on implementing comprehensive input validation and output encoding for all user-supplied data that enters the redirect functionality. Organizations should upgrade to SSL-Explorer version 0.2.13 or later, which contains the necessary patches to address this vulnerability. Additionally, implementing proper parameter validation for the forwardTo parameter, including strict sanitization of input values, can prevent malicious content from being processed. The solution should incorporate security measures aligned with ATT&CK technique T1203, which involves exploiting weaknesses in web application input validation. Security teams should also consider implementing web application firewalls and content security policies to provide additional layers of protection against similar vulnerabilities in the future.
