Patch Published: N/A
CVE [?]: CVE-2004-0397
CPE [?]: N/A

Synopsis

The remote service is vulnerable to a buffer overflow.

Description

The remote host is vulnerable to a remote stack-based overflow. An attacker, exploiting this hole, would be given full access to the target machine. Versions of Subversion less than 1.0.3 are vulnerable to this attack. This vulnerability was discovered by Stefan Esser and posted to public mailing lists.

Solution

Upgrade to version 1.0.3 or higher

Public Exploits

Target Network Port(s): N/A
Target Asset(s): Services/subversion
Exploit Available: True (Metasploit Framework, Exploit-DB, Immunity Canvas)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the Subversion < 1.0.3 apr_time_t data Conversion Remote Overflow vulnerability:

  1. Metasploit: exploit/multi/svn/svnserve_date
    [Subversion Date Svnserve]
  2. Exploit-DB: exploits/unix/dos/16284.rb
    [EDB-16284: Subversion - Date Svnserve (Metasploit)]
  3. Exploit-DB: exploits/multiple/remote/9935.rb
    [EDB-9935: Subversion 1.0.2 - Date Overflow (Metasploit)]
  4. Immunity Canvas: CANVAS

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.

WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.
