Vulnerabilities (Page 7)

From XSS to RCE (dompdf 0day)

web

A chain of issues going from an XSS to a remote file download in a server-side PDF renderer, leading to remote-code execution.The XSS initally seemed a bit weak as the application had no secrets or even authentication so attacking other users would not provide much gain…

 

cr8escape: New Vulnerability in CRI-O Container Engine [CVE-2022-0811]

Simple container escape compared to several we’ve covered in the past, the sysctls passed into the pinns utility are delimited by a + which can be maliciously included in a value to inject otherwise blocked sysctls. There is some minimal validation on the sysctls being passed in to ensure the keys don’t match any sensitive keys, however an attacker can set a value to +sensitive.key=othervalue to smuggle in a blocked option.

 

Branch History Injection

An attack which extends upon branch target injection, which is an attack where you train the branch predictor on an indirect branch to speculatively execute a branch erroneously and side-channel the cache to leak data.One of the various mitigations introduced by Intel and ARM were Enhanced Indirect Branch Restricted Speculation (eIBRS) and CSV2 respectively…

 

Multiple Vulnerabilities in Passcom Leading to Unauthenticated RCE

web

A nice chain leading to unauthenticated RCE, a path traversal leading to server-side request forgery, used to hit the application’s API from localhost and leak administrative credentials, then an unescaped argument in a privileged-off task for command injection.
