- 漏洞讨论

TWiki is prone to an information-disclosure vulnerability. The application fails to properly sanitize user-supplied input.

Attackers may gain access to arbitrary, restricted content files with the privileges of the hosting webserver. This can aid in further attacks.

- 漏洞利用

This issue can be exploited through use of a web client.

- 解决方案

The vendor has released a hotfix. Symantec has not tested the integrity or effectiveness of the hotfix.

Hotfix for rdiff script:

In file twiki/lib/TWiki/UI/, find sub diff. 10 lines lower in the file you will find the following line:

TWiki::UI::checkTopicExists( $session, $webName, $topic, 'diff' );

Add the following line immediately after it:

TWiki::UI::checkAccess( $session, $webName, $topic, 'view', $session->{user} );

CVE-2006-1386_UI_RDiff_pm.diff: Patch for twiki/lib/TWiki/UI/, TWiki 4.0.1 (See HowToApplyPatch)

Hotfix for preview script:

In file twiki/lib/TWiki/UI/ find the following lines:

if( $topicExists ) {
( $prevMeta, $prevText ) =
$store->readTopic( undef, $webName, $topic, undef );
if( $prevMeta ) {
foreach my $k ( keys %$prevMeta ) {

Change the call to 'readTopic' to:

$store->readTopic( $user, $webName, $topic, undef );
