Command Execution Vulnerability in Cockpit by Red Hat

CVE-2026-4802

What is CVE-2026-4802?

CVE-2026-4802 is a command execution vulnerability found in Cockpit, a web-based interface for managing servers, developed by Red Hat. This vulnerability arises due to the mishandling of user-controlled parameters within the system logs user interface. An attacker can exploit this flaw by crafting specific links that include unsanitized shell metacharacters and command substitutions. By doing so, the attacker can achieve arbitrary command execution on the host system, leading to severe consequences, including potential full system compromise. The ability to execute arbitrary shell commands opens up a host of security risks, ranging from unauthorized data access to complete control over critical server resources, thereby adversely affecting organizational operations and security integrity.

Potential impact of CVE-2026-4802

1. Full System Compromise: Exploiters can execute arbitrary commands, which can lead to unauthorized access and control, threatening the confidentiality and integrity of sensitive data within the organization.

2. Data Breaches: The execution of malicious commands could facilitate data exfiltration or manipulation, resulting in significant breaches that have legal, financial, and reputational repercussions for the organization.

3. Increased Vulnerability to Ransomware and Malware Attacks: The ability to execute commands provides attackers a pathway to install malware or ransomware, potentially leading to widespread disruptions and requiring costly remediation efforts.
