Description

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, 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 script injection.

  "executiveSummary": "Dell Secure Connect Gateway (SCG) 5.0 is susceptible to an Improper Neutralization of Special Elements used in an OS Command vulnerability, classified as OS Command Injection.\nThis security flaw allows an unauthenticated, remote attacker to execute unauthorized commands on the underlying host operating system.\nThe vulnerability affects Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00.\nSuccessful exploitation poses a critical risk to the integrity, availability, and confidentiality of the appliance, as it permits arbitrary code execution without prior authentication.\nThe attack vector is network-based, meaning any remote actor capable of reaching the appliance can potentially trigger the injection.\nImmediate patching is required to neutralize the threat and prevent unauthorized access to the appliance's management environment.",
  "technicalDetails": "The vulnerability exists due to insufficient input validation and sanitization of user-supplied data processed by the Dell SCG 5.0 system. Specifically, the application fails to adequately neutralize special characters or command sequences before passing them to system-level calls or shell interpreters.\nThe core issue involves an OS Command Injection vulnerability where an attacker can supply malicious payloads containing system command delimiters (such as semicolons, pipes, or backticks). When these payloads are processed by the vulnerable component, the underlying operating system executes the injected commands with the privileges of the application process.\nThe attack flow initiates with the attacker sending a crafted, malicious request to the vulnerable Dell SCG endpoint. Because the application does not verify the integrity or safety of the input, the malicious string is interpreted as a legitimate command instruction by the host shell. By manipulating the input stream, an unauthenticated attacker can effectively break out of the application's intended execution context.\nThe exploitation does not require prior authentication or elevated privileges, significantly increasing the attack surface. Remote exposure via the network interface allows an attacker to interact with the vulnerable service from any external location with network connectivity to the appliance.\nUpon successful injection, the payload behavior is limited only by the permissions of the user account running the SCG service. An attacker could potentially retrieve sensitive configuration files, modify system settings, install persistent backdoors, or pivot further into the internal network infrastructure.\nThe affected versions are strictly identified as Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00. The vulnerability stems from a failure to strictly whitelist input or implement proper parameterization when interacting with the OS layer.\nPost-exploitation, the impact is severe. An attacker gains the ability to execute arbitrary shell commands, which may lead to full system compromise, data exfiltration, or the deployment of malware. Remediation requires updating to the specified patched versions to ensure that command input is properly handled and sanitized."
