Description Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2005-08-14 21:59:03 UTC
Stefan Esser discovered:  
a logical error that allows  an attacker to nest XML tags in a way, that a  
single doublequote will be  appended to the eval string. The next string tag  
will add another  doublequote, then the string data and a closing doublequote.  
It should  be obvious that this means the stringdata is not handled as string  
but  as actual code due to this.

Comment 4 Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2005-08-17 09:03:31 UTC
There is an error in the patch: 
+    case 'DATETIME.ISO8601': 
+        $XML_RPC_xh[$parser]['vt'] = $GLOBALS['XML_RPC_DateTime']; 
+       $XML_RPC_xh[$parser]['value'] = base64_decode($XML_RPC_xh[$parser]
the base64_decode() call should not be there.

Keeping this bug for PEAR XML-RPC only.

Fixed version is PEAR XML_RPC 1.4.0
Comment 7 Sebastian Bergmann (RETIRED) gentoo-dev 2005-08-18 10:17:31 UTC
dev-php/PEAR-XML_RPC-1.4.0 is already in the tree and marked stable.
