Warning: New attack campaign utilized a new 0-day RCE vulnerability on Microsoft Exchange Server
Circa the beginning of August 2022, while doing security monitoring & incident response services, GTSC SOC team discovered that a critical infrastructure was being attacked, specifically to their Microsoft Exchange application. During the investigation, GTSC Blue Team experts determined that the attack utilized an unpublished Exchange security vulnerability, i.e., a 0-day vulnerability, thus immediately came up with a temporary containment plan.

CISA received seven files for analysis. Six Java Server Pages (JSP) webshells and a Bourne Again SHell (bash) file. Five JSP webshell files are designed to parse inbound requests for commands for execution, download files, and upload files. One JSP webshell file contains a form with input fields that prompts the attacker to enter the command in the input box and click "run" to execute. The command output will be displayed in a JSP page. The bash file is designed to perform ldapsearch queries and store the output into a newly created directory.

Tarfile: Exploiting the World With a 15-Year-Old Vulnerability
Tarfile: Exploiting the World With a 15-Year-Old Vulnerability
Trellix Advanced Research Center stumbled across a vulnerability in Python’s tarfile module. As we dug into the issue, we realized this was in fact CVE-2007-4559. The vulnerability is a path traversal attack in the extract and extractall functions in the tarfile module that allow an attacker to overwrite arbitrary files by adding the “..” sequence to filenames in a TAR archive. Over the course of our research into the impact of this vulnerability we discovered that hundreds of thousands of repositories were vulnerable to this vulnerability. While the vulnerability was originally only marked as a 6.8, we were able to confirm that in most cases an attacker can gain code execution from the file write.
