This is a whitepaper tutorial that describes steps taken to identify post-authentication remote code execution vulnerabilities in Symantec Web Gateway version 5.0.2.8.

Facebook suffered from an information disclosure vulnerability. If a user uploaded their contacts to Facebook and then proceeded to download their expanded dataset from the DYI (Download Your Information) section, they would receive a file called addressbook.html in their downloaded archive. The addressbook.html is supposed to house the contact information they uploaded. However, due to a flaw in how Facebook implemented this, it also housed contact information from other uploads other users have performed for the same person, provided they had one piece of matching data. This effectively built large dossiers on users and disclosed their information to anyone that knew at least one piece of matching data.

Oracle Java versions prior to 7u25 suffer from an invalid array indexing vulnerability that exists within the native storeImageArray() function inside jre/bin/awt.dll. This exploit code demonstrates remote code execution by popping calc.exe. It was obtained through the Packet Storm Bug Bounty program.

Oracle Java versions prior to 7u25 suffer from an invalid array indexing vulnerability that exists within the native storeImageArray() function inside jre/bin/awt.dll. This vulnerability allows for remote code execution. User interaction is required for this exploit in that the target must visit a malicious page or open a malicious file. This finding was obtained through the Packet Storm Bug Bounty program.

The IntegerInterleavedRaster.verify() method in Oracle Java versions prior to 7u25 is vulnerable to a signed integer overflow that allows bypassing of "dataOffsets[0]" boundary checks. This exploit code demonstrates remote code execution by popping calc.exe. It was obtained through the Packet Storm Bug Bounty program.

The IntegerInterleavedRaster.verify() method in Oracle Java versions prior to 7u25 is vulnerable to a signed integer overflow that allows bypassing of "dataOffsets[0]" boundary checks.

This finding was purchased through the Packet Storm Bug Bounty program.

Adobe ColdFusion versions 9.0, 9.0.1, and 9.0.2 do not properly check the "rdsPasswordAllowed" field when accessing the Administrator API CFC that is used for logging in. The login function never checks if RDS is enabled when rdsPasswordAllowed="true". This means that if RDS was not configured, the RDS user does not have a password associated with their username. This means by setting rdsPasswordAllowed to "true", we can bypass the admin login to use the rdsPassword, which in most cases, is blank. These details were purchased through the Packet Storm Bug Bounty program and are being released to the community.

The BytePackedRaster.verify() method in Oracle Java versions prior to 7u25 is vulnerable to a signed integer overflow that allows bypassing of "dataBitOffset" boundary checks. This exploit code demonstrates remote code execution by popping calc.exe. It was obtained through the Packet Storm Bug Bounty program.

The ByteComponentRaster.verify() method in Oracle Java versions prior to 7u25 is vulnerable to a memory corruption vulnerability that allows bypassing of "dataOffsets[]" boundary checks. This exploit code demonstrates remote code execution by popping calc.exe. It was obtained through the Packet Storm Bug Bounty program.

This exploit leverages both invalid typecast and memory disclosure vulnerabilities in Microsoft Silverlight 5 in order to achieve code execution. This exploit code demonstrates remote code execution by popping calc.exe. It was obtained through the Packet Storm Bug Bounty program. Google flags this as malware so only use this if you know what you are doing. The password to unarchive this zip is the word "infected".

Microsoft Silverlight 5 suffers from invalid typecast and memory disclosure vulnerabilities that, when leveraged together, allow for arbitrary code execution. A memory disclosure vulnerability exists in the public WriteableBitmap class from System.Windows.dll. This class allows reading of image pixels from the user-defined data stream via the public SetSource() method. BitmapSource.ReadStream() allocates and returns byte array and a count of array items as out parameters. These returned values are taken from the input stream and they can be fully controlled by the untrusted code. When returned "count" is greater than "array.Length", then data outside the "array" are used as input stream data by the native BitmapSource_SetSource() from agcore.dll. Later all data can be viewed via the public WriteableBitmap.Pixels[] property. Exploitation details related to these findings were purchased through the Packet Storm Bug Bounty program.

Proof of concept code that demonstrates an ASLR bypass of PIE compiled 64bit Linux.

The release of this advisory provides exploitation details in relation a weakness in the Linux ASLR implementation. The problem appears when the executable is PIE compiled and it has an address leak belonging to the executable. These details were obtained through the Packet Storm Bug Bounty program and are being released to the community.

Druva inSync Windows Client version 6.5.2 suffers from a local privilege escalation vulnerability.

Asterisk Project Security Advisory - The RTP support in Asterisk maintains its own registry of dynamic codecs and desired payload numbers. While an SDP negotiation may result in a codec using a different payload number these desired ones are still stored internally. When an RTP packet was received this registry would be consulted if the payload number was not found in the negotiated SDP. This registry was incorrectly consulted for all packets, even those which are dynamic. If the payload number resulted in a codec of a different type than the RTP stream (for example the payload number resulted in a video codec but the stream carried audio) a crash could occur if no stream of that type had been negotiated. This was due to the code incorrectly assuming that a stream of the type would always exist.

Trend Micro Maximum Security is vulnerable to arbitrary code execution as it allows for creation of registry key to target a process running as SYSTEM. This can allow a malware to gain elevated privileges to take over and shutdown services that require SYSTEM privileges like Trend Micros "Asmp" service "coreServiceShell.exe" which does not allow Administrators to tamper with them. This could allow an attacker or malware to gain elevated privileges and tamper with protected services by disabling or otherwise preventing them to start. Note administrator privileges are required to exploit this vulnerability.

A remote attacker could possibly use this issue to perform a session fixation attack. Various other issues were also addressed.
