Malicious builds and wider infrastructural compromise were worst-case scenarios

IBM PowerVM VIOS 3.1 could allow a remote attacker to tamper with system configuration or cause a denial of service. IBM X-Force ID: 230956.

New web targets for the discerning hacker

sqclass.cpp in Squirrel through 2.2.5 and 3.x through 3.1 allows an out-of-bounds read (in the core interpreter) that can lead to Code Execution. If a victim executes an attacker-controlled squirrel script, it is possible for the attacker to break out of the squirrel script sandbox even if all dangerous functionality such as File System functions has been disabled. An attacker might abuse this bug to target (for example) Cloud services that allow customization via SquirrelScripts, or distribute malware through video games that embed a Squirrel Engine.

A path traversal vulnerability exists within GoAnywhere MFT before 6.8.3 that utilize self-registration for the GoAnywhere Web Client. This vulnerability could potentially allow an external user who self-registers with a specific username and/or profile information to gain access to files at a higher directory level than intended.

Ahead of their Black Hat USA talk in August, Simon Pavitt and Stephen Dewsnip explain the value of helping people practice cyber defense via a "malicious floorwalker" exercise.

By Francesco Benvenuto.  Recently, I was performing some research on a wireless router and noticed the following piece of code:  This unescape function will revert the URL encoded bytes to its original form. But something specifically caught my attention: There was no size check for the performed operations and the function assumes that after a ‘%’ there are always two bytes. So, what would happen if after ‘%’, only one character existed? The answer is that the s+3, in the strcpy, will access after the end of the string. So, it could lead to memory corruption. Then, I tried to exploit this bug on the router in question. But based on how the URL string was managed in that device, it was not possible. But it had the potential to crash other web servers that used this piece of code. That function belonged to the freshtomato library. So, I searched for the source code and noticed that at the beginning of the file containing that function, there was the following comment:  It was code fr...
