Loss of Integrity Patch / RCS
Exploit Commercial

- 漏洞描述

A remote overflow exists in the RSA SecurID Web Agent. The Web Agent fails to large "chunks" of data sent via the chunked-encoding mechanism resulting in a heap overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.

- 漏洞讨论

A remote heap-based buffer overflow vulnerability exists in RSA Authentication Agent for Web. This issue is due to a failure of the application to properly bounds check user-supplied input data prior to copying it into a fixed-sized heap buffer memory region.

This vulnerability allows remote attackers to execute arbitrary machine code in the context of the vulnerable server application. This reportedly occurs with 'LocalSystem' privileges, allowing the attacker to gain complete control of the targeted computer.

Versions 5.0, 5.2, and 5.3 of RSA Authentication Agent for Web are vulnerable to this issue.

- 漏洞利用

The discoverer has reportedly developed an exploit. This exploit is not publicly available or known to be circulating in the wild.

An exploit ( as part of the Metasploit Framework has been released.
