Red Hat Linux DHCP Client Found Vulnerable to Command Injection Attacks

Red Hat Linux DHCP Client Found Vulnerable to Command Injection Attacks

May 15, 2018
A Google security researcher has discovered a critical remote command injection vulnerability in the DHCP client implementation of Red Hat Linux and its derivatives like Fedora operating system. The vulnerability, tracked as CVE-2018-1111 , could allow attackers to execute arbitrary commands with root privileges on targeted systems. Whenever your system joins a network, it's the DHCP client application which allows your system to automatically receive network configuration parameters, such as an IP address and DNS servers, from the DHCP (Dynamic Host Control Protocol) server. The vulnerability resides in the NetworkManager integration script included in the DHCP client packages which is configured to obtain network configuration using the DHCP protocol. Felix Wilhelm from the Google security team found that attackers with a malicious DHCP server, or connected to the same network as the victim, can exploit this flaw by spoofing DHCP responses, eventually allowing them to run

Midnight Blizzard and Cloudflare-Atlassian Cybersecurity Incidents: What to Know

Feb 13, 2024SaaS Security / Data Breach
The Midnight Blizzard and Cloudflare-Atlassian cybersecurity incidents raised alarms about the vulnerabilities inherent in major SaaS platforms. These incidents illustrate the stakes involved in SaaS breaches — safeguarding the integrity of SaaS apps and their sensitive data is critical but is not easy. Common threat vectors such as sophisticated spear-phishing, misconfigurations and vulnerabilities in third-party app integrations demonstrate the complex security challenges facing IT systems. In the case of Midnight Blizzard, password spraying against a test environment was the initial attack vector. For Cloudflare-Atlassian, threat actors initiated the attack via compromised  OAuth tokens  from a prior breach at Okta, a SaaS identity security provider.  What Exactly Happened?
