Description

Dell ThinOS 10, versions prior to 2605_10. 2616, contains an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Command execution.

  "executiveSummary": "Dell ThinOS 10 versions prior to 2605_10.2616 are affected by an Improper Neutralization of Special Elements used in an OS Command, classified as an OS Command Injection vulnerability.\nThis vulnerability allows a high-privileged, remote attacker to execute arbitrary system commands on the underlying operating system.\nThe flaw presents a significant security risk, as successful exploitation results in full remote code execution, potentially allowing the attacker to bypass access controls, escalate privileges further, or manipulate the thin client environment.\nExploitation requires the attacker to possess high-privileged remote access to the target system prior to initiating the attack.\nGiven the nature of the vulnerability, the impact spans the confidentiality, integrity, and availability of the affected ThinOS device.",
  "technicalDetails": "The vulnerability resides within Dell ThinOS 10 due to insufficient input validation and sanitization of user-supplied data before it is passed to a system shell or command execution API.\nThe root cause is identified as an Improper Neutralization of Special Elements used in an OS Command (CWE-78). When the application constructs system-level commands, it fails to properly sanitize metacharacters—such as semicolons, pipes, or backticks—that modify command execution logic.\nAn attacker with high-privileged remote access can leverage this flaw by injecting crafted input strings into specific interfaces or configuration parameters that the ThinOS backend processes without adequate filtering.\nThe attack flow follows a structured trajectory: First, the attacker identifies a component or function within the operating system environment that fails to neutralize malicious shell metacharacters. Second, the attacker transmits a specifically crafted payload containing shell commands designed to execute outside the intended scope. Third, the operating system's command interpreter parses the input, treats the malicious string as part of the intended system command, and executes the injected instructions with the elevated privileges associated with the vulnerable process.\nBecause the execution occurs with high privileges, the injected commands can perform arbitrary operations, such as modifying system configurations, exfiltrating sensitive credentials stored in memory, or establishing persistence mechanisms to maintain unauthorized access.\nAffected versions are strictly limited to those identified as being prior to 2605_10.2616. The vulnerability requires existing high-privileged access, implying that the attack vector is likely internal or leveraged by a compromised service account within the remote management framework.\nThe impact of a successful exploitation is severe, as it facilitates complete subversion of the ThinOS device's integrity. By manipulating the execution flow, an adversary can bypass existing security policy enforcements, effectively gaining control over the thin client infrastructure."
