Synopsis |
19 |
======== |
20 |
|
21 |
A vulnerability in Chora allows remote code execution and file upload. |
22 |
|
23 |
Background |
24 |
========== |
25 |
|
26 |
Chora is a PHP-based SVN/CVS repository viewer by the HORDE project. |

================= |

Description |
37 |
=========== |
38 |
|
39 |
A vulnerability in the diff viewer of Chora allows an attacker to |
40 |
inject shellcode. An attacker can exploit PHP's file upload |
41 |
functionality to upload a malicious binary to a vulnerable server, |
42 |
chmod it as executable, and run the file. |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
An attacker could remotely execute arbitrary binaries with the |
48 |
permissions of the PHP script, conceivably allowing further |
49 |
exploitation of local vulnerabilities and remote root access. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All users are advised to upgrade to the latest version of Chora: |
60 |
|
61 |
# emerge sync |
62 |
|
63 |
# emerge -pv ">=net-www/horde-chora-1.2.2" |
64 |
# emerge ">=net-www/horde-chora-1.2.2" |
