New MS Office Zero-Days

FYI...

- http://www.avertlabs.com/research/blog/?p=253
April 10, 2007 ~ "Some of these flaws may allow for remote code execution. McAfee Avert Labs is investigating all these zero-days. Today is Patch Tuesday for April. So, yes: this is yet another time that zero-day flaws have been published around a Patch Tuesday, possibly to maximize the public’s exposure to these flaws until the next month’s Patch Tuesday.
Update, 2pm PST
Further research by Avert Labs indicates that all but one of the Office zero-days reported yesterday result in denial of service. There is one heap-overflow flaw that might be exploited for code execution. We’ll keep you updated.
Update, 5pm PST
Avert Labs has been analyzing proof-of-concept code for a zero-day vulnerability in Microsoft Windows’s handling of HLP files. This is another heap-overflow flaw that might be exploited for code execution. Stay tuned."

Apr 10 2007 ~ "... McAfee is still investigating the security vulnerabilities. They may not actually all be new, said Dave Marcus, security research and communications manager at (McAfee). "Sometimes what people claim to be zero-days may in fact be related to something that's already known," he said. Should the three Office bugs be new, the tally of zero-day vulnerabilities in the productivity suite waiting for a fix would jump to five. Microsoft did not deliver any patches for Office on Tuesday*..."

Microsoft Security Advisory (935964)
Vulnerability in RPC on Windows DNS Server Could Allow Remote Code Execution.
- http://www.microsoft.com/technet/security/advisory/935964.mspx
April 12, 2007 ~ "Microsoft is investigating new public reports of a limited attack exploiting a vulnerability in the Domain Name System (DNS) Server Service in Microsoft Windows 2000 Server Service Pack 4, Windows Server 2003 Service Pack 1, and Windows Server 2003 Service Pack 2..."

Last Updated: 2007-04-13 04:42:08 UTC ...(Version: 2)
"...Microsoft has a few suggested actions that can mitigate the risk with the caveat that some tools may break.
1. Disable remote management over RPC for the DNS server via a registry key setting.
2. Block unsolicited inbound traffic on ports 1024-5000 using IPsec or other firewall.
3. Enable the advanced TCP/IP Filtering options on the appropriate interfaces of the server..."

Last Updated: 2007-04-13 21:06:53 UTC ~ "...We have knowledge of a successful attack that occurred on April 4, 2007. This appears to be an opportunistic attack (instead of a targeted attack). So it's likely that others have been compromised as well. If you have a vulnerable MS DNS server (Win2K SP4 or Win2003 SP1 or SP2) accessible to the Internet and don't have ports above 1024 blocked, then you may have already been targeted in an attack. At this point, there seems to be a very small number of known compromises...
Update: If you have a large number of domain controllers and want to automate the disabling of RPC, check out this blog entry: http://preview.tinyurl.com/2ymwsv "

Last Updated: 2007-04-14 14:30:08 UTC ...(Version: 2)
"Update 2: We have two confirmed sources that were attacked on April 4th and 5th. Both were universities in the US. The initial report was from the Information Security Office at Carnegie Mellon University. Nice catch guys! The attacking source IP was the same in both cases: 61.63.227.125
Here is the attack details from the Carnegie Mellon folks. First, a TCP port scan to ports 1024-2048. Then a TCP connection to the right TCP port running the vulnerable RPC service. Shellcode binds to TCP port 1100. Attacker uploads a VBscript on this port and then runs it. VBscript downloads an executable DUP.EXE (MD5: a5ae220fec052a1f2cd22b4eb89a442e) from 203.66.151.92/images/. Executable is self-extracting and contains PWDUMP v5 and an associated DLL.
Update 3: There is now a publicly available exploit for this vulnerability in Metasploit 3"

"...UPDATE:
- Microsoft has now added that for users with valid authentication credentials, exploitation may be possible over port 445.
- A public exploit now appears to be available that supports the port 445 vector and support Windows 2003 Server SP2...
- Microsoft added to their advisory that DNS server local administration and configuration may not work if the computer name is 15 characters of longer. They suggest using the FQDN (Fully Qualified Domain Name) of the host to ensure this works correctly."

...Scanning for port 1025 DNS/RPC

Last Updated: 2007-04-16 22:27:56 UTC ...(Version: 3)
"We are currently tracking a new version of the Rinbot worm that in addition to its regular scans, is also scanning for port 1025/tcp. Once connected, it attempts to do a Windows 2000 DnsservQuery, attempting to exploit the recent Microsoft DNS RPC vulnerability. Detection of this virus is currently very poor, and we are working with the AV vendors to improve this:
