py-cryptography -- allows programmers to misuse an API

alex reports: Previously, Cipher.updateinto would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects such as bytes to be mutated, thus violating fundamental rules of Python. This is a soundness bug -- it allows...

Immutable varibles should be checked to there default values

Lines of code Vulnerability details Impact It is very important to check whether the immutable variables are not equal to the default values because if Quest is created and when we pass a default value to a variable then it can't be changed and it can lead to a problem. Proof of Concept Suppose...

Siemens S7-1500 CPU devices Missing Immutable Root of Trust in Hardware (CVE-2022-38773)

Affected devices do not contain an Immutable Root of Trust in Hardware. With this the integrity of the code executed on the device can not be validated during load-time. An attacker with physical access to the device could use this to replace the boot image of the device and execute arbitrary cod...

The vulnerability of microprogrammed software in Siemens SIMATIC S7-1500 CPU Family programmable logic controllers stems from the lack of an immutable root cause in the equipment. This allows a hacker to replace the device’s load image and execute arbitrary code.

The vulnerability of the microprogrammed control systems of Siemens SIMATIC S7-1500 CPU Family lies in the absence of an immutable trust base in the equipment. Exploiting this vulnerability allows a perpetrator to replace the device’s boot image and execute arbitrary code...
