[原文]Direct static code injection vulnerability in error.php in GuppY 4.5.9 and earlier, when register_globals is disabled, allows remote attackers to execute arbitrary PHP code via the _SERVER[REMOTE_ADDR] parameter, which is injected into a .inc script that is later included by the main script.


[CNNVD]GuppY error.php直接静态代码注入漏洞(CNNVD-200511-480)

        GuppY 是一款在终端使用的小型 Web 入口,不需要数据库的运行。
        GuppY 4.5.9及更早版本的error.php存在直接静态代码注入漏洞,在启用register_globals时,可让远程攻击者通过_SERVER[REMOTE_ADDR]参数(该参数会注入稍后将包含在主要脚本中的a .inc脚本)执行任意PHP代码。

Yes No
2005-11-28 12:00:00 2007-11-15 12:36:00
Discovered by rgod.

- 受影响的程序版本

Guppy GuppY 4.5.16
Guppy GuppY 4.5.9
Guppy GuppY 4.5.4
Guppy GuppY 4.5.3 a
Guppy GuppY 4.5.3
Guppy GuppY 4.5

- 漏洞讨论

GuppY is prone to a remote file-include vulnerability and to a command-execution vulnerability.

The software fails to properly sanitize data supplied to the 'error.php' script, allowing attackers to specify remotely hosted script files to be executed in the context of the webserver hosting the vulnerable software.

An attacker can exploit this issue to execute arbitrary remote PHP code on an affected computer with the privileges of the webserver process.

An attacker can also pass malicious PHP commands through this script to be executed on an affected server, which could facilitate unauthorized access as well.

GuppY 4.5.16 and prior versions are vulnerable.

- 漏洞利用

An exploit is not required.

Proof-of-concept examples are available:
http://www.example.com/[path_to_guppy]/error.php?err=hacker&_SERVER=&_SERVER[REMOTE_ADDR]=";passthru("ls -la>README");echo"

- 解决方案

Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or if you are aware of more recent information, please mail us at: mailto:vuldb@securityfocus.com.
