A Security Vulnerability in the Sun Java System Directory Server May Allow Users to Probe for Filenames and View Limited Content of Files

1. Impact

A security vulnerability in the Online Help feature of Sun Java System Directory Server 5.2 may allow a local or remote unprivileged user to determine if particular files or directories exist on the system. In certain cases, a single line of a file's contents may be revealed as well.

Sun acknowledges with thanks, the National Australia Bank's Security Assurance Team for for the discovery and reporting of this vulnerability.

2. Contributing Factors

This issue can occur in the following releases for Solaris 9 and 10 on Solaris SPARC and Solaris x86 Platforms, Linux, Windows, and HP-UX:

PatchZIP (Compressed Archive) and Native package versions:

• Sun Java System Directory Server Enterprise Edition 5
• Sun Java System Directory Server 5.2

Note: Sun Java System Directory Server Enterprise Edition 6.x is not affected by this issue.

To determine the version of Sun Java System Directory Server running on a system, the following command can be run:

On Solaris, Linux, HP-UX, and AIX systems:

$ cd <installation directory>/bin/slapd/server
$ ./ns-slapd -V -D <instance-directory>
Sun Java(TM) System Directory Server/5.2    

On 64-bit Solaris:

$ cd <installation directory>/bin/slapd/server/64
$ ./ns-slapd -V -D <instance-directory>
Sun Java(TM) System Directory Server/5.2

On 64-bit HP-UX:

$ cd <installation directory>/bin/slapd/server/pa20_64
$ ./ns-slapd -V -D <instance-directory>
Sun Java(TM) System Directory Server/5.2

On Windows systems:

>cd <installation directory>/bin/slapd/server
>slapd.exe -V -D <instance-directory>

3. Symptoms

There are no predictable symptoms that would indicate the described issue has been exploited to probe for files or directories on the system.

4. Workaround

To work around this issue, disable the online help by removing the file '<install-dir>/manual/help/help'.

5. Resolution

This issue is addressed in the following release for Solaris 9 and 10 on Solaris SPARC and Solaris x86 Platforms, Linux, Windows, and HP-UX:
