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. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Command execution.

  "executiveSummary": "Dell ThinOS 10 is susceptible to an OS Command Injection vulnerability due to improper neutralization of special elements used in system commands. This security flaw allows a remote, unauthenticated attacker to execute arbitrary commands on the underlying operating system of the affected thin client.\nThe vulnerability represents a critical risk as it enables unauthorized system control, potentially compromising the integrity, confidentiality, and availability of the thin client device. By leveraging this flaw, an attacker could bypass standard security controls, perform unauthorized actions, or establish persistent access.\nThe scope of impact includes all Dell ThinOS 10 deployments running versions prior to 2605_10. 2616. Remediation requires an immediate update to the identified secure version or higher to eliminate the injection vector. The exposure is categorized as high risk given the remote exploitability and the lack of authentication required to initiate the attack sequence.",
  "technicalDetails": "The vulnerability resides within the command-processing logic of Dell ThinOS 10, specifically where user-supplied input or network-derived data is passed to system-level shells or OS-native execution functions without adequate validation or escaping.\nThe root cause is identified as an Improper Neutralization of Special Elements used in an OS Command (CWE-78). The application fails to strictly sanitize input strings, allowing an attacker to inject shell metacharacters such as semicolons, pipes, or backticks. When the system processes these strings, the underlying OS interpreter interprets the injected characters as control operators, thereby executing arbitrary commands with the privileges of the service or process initiating the call.\nExploitation is feasible over the network, as the interface responsible for processing the vulnerable input is accessible to unauthenticated remote attackers. The attack flow involves the adversary crafting a malicious payload—typically containing shell command sequences—and transmitting it through the exposed network service. Upon reaching the vulnerable component, the payload is concatenated with legitimate command parameters and passed to the shell execution environment.\nBecause the system performs insufficient input validation, the injected command is executed concurrently with the legitimate intended function. This allows the attacker to perform arbitrary actions, such as initiating unauthorized network connections, exfiltrating configuration data, or modifying system state. The impact is significant as it grants command execution capability at the operating system level without the need for prior credentials.\nThe vulnerable component remains susceptible across all iterations of ThinOS 10 prior to the version 2605_10. 2616 release. The lack of proper boundary checking on input parameters facilitates this injection flow. Post-exploitation, an attacker can utilize the device as a pivot point for lateral movement within the network or maintain persistence by altering local system configurations. Since the execution occurs within the context of the vulnerable process, any limitations on the process's runtime environment define the initial scope of the attacker's capabilities, though the primary risk remains complete loss of control over the ThinOS endpoint."
