[原文]Jaws 0.3 allows remote attackers to bypass authentication and via an HTTP request to admin.php with the logged cookie set to the MD5 hash of a null password, which is compared against the logged session variable by the logged_on function in application.php.
JAWS is reported prone to multiple vulnerabilities. The issues result from insufficient sanitization of user-supplied data. The following specific issues can affect the application:
JAWS is prone to a cross-site scripting vulnerability.
This cross-site scripting issue can permit a remote attacker to create a malicious URI link that includes hostile HTML and script code. If a user follows the malicious link, the attacker-supplied code executes in the Web browser of the victim computer. This attack can allow for theft of cookie-based authentication credentials and other attacks.
JAWS is reported to be prone to a file disclosure vulnerability. The vulnerability presents itself because directory traversal sequences "../.." are not correctly sanitized from user-supplied data. It is reported that an attacker may disclose a target file by including a relative path including directory traversal sequences to the target file as a value for URI parameters passed to the a JAWS script.
An authentication bypass vulnerability is reported to affect the JAWS authentication system. It is reported that an authentication cookie is derived from a known value, a remote attacker may create a cookie and use this cookie to authenticate to the system.
Currently, there are no known workarounds or upgrades to correct this issue. However, Jaws has released a patch to address this vulnerability.
