PoC Exploit for SharePoint RCE – CVE-2023-29357 & CVE-2023-24955
Jang a security researcher has unveiled an exploit chain linking two distinct vulnerabilities in Microsoft SharePoint Server: CVE-2023-29357 and CVE-2023-24955 during Pwn2Own Vancouver March 2023 edition. This chain was not just a theoretical exercise; it enabled remote code execution (RCE) against the server, a feat that captured the attention of cybersecurity enthusiasts and professionals alike.
Later during the month of September 2023, Jang detailed out this exploit chain, followed by the release of a proof-of-concept (PoC) on GitHub for CVE-2023-29357. The authors of the PoC took an ethical stance, ensuring that RCE wasn’t achievable with the current PoC.
Terrapin Attack in OpenSSH
Security researchers have identified a new threat targeting the integrity of Secure Shell (SSH) communications called as the Terrapin Attack.
The Terrapin Attack is a prefix truncation assault against the SSH protocol, disrupting the security of the SSH channel. By adjusting sequence numbers during the handshake process, attackers can covertly remove crucial messages from either the client or server, undetected. This vulnerability not only jeopardizes the channel’s integrity but also downgrades connection security, potentially leading to the use of less secure client authentication algorithms and disabling vital countermeasures against keystroke timing attacks.
