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. A low privileged attacker with local access could potentially exploit this vulnerability, leading to command execution.

  "executiveSummary": "This vulnerability involves an Improper Neutralization of Special Elements used in an OS Command (OS Command Injection) within Dell SCG 5.0 Appliance and Application versions.\nThe flaw allows a low-privileged, locally authenticated attacker to execute arbitrary system commands with elevated privileges, potentially compromising the integrity and availability of the appliance.\nAffected products include 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.\nThe risk implication is significant as successful exploitation grants the attacker the ability to interact directly with the underlying operating system.\nExploitation requires the attacker to already possess local access to the target environment, which serves as a prerequisite for triggering the vulnerable command execution path.",
  "technicalDetails": "The vulnerability originates from a failure to sufficiently sanitize user-supplied input before passing it to system-level command execution functions within the Dell SCG appliance environment.\nRoot cause analysis indicates that the application improperly neutralizes special characters or sequences that act as shell metacharacters, allowing an attacker to escape the intended command context and inject arbitrary OS-level instructions.\nAn attacker with low-privileged local access can leverage this defect by providing crafted input into exposed application interfaces that invoke internal system processes or scripts.\nUpon processing the malicious input, the application shell executes the attacker-supplied payload concurrently or sequentially with the legitimate command, effectively bypassing the security boundary intended for the low-privileged user.\nBecause the vulnerable component interacts with the underlying operating system with higher-level permissions than the authenticated user, the injected commands are executed in a context that may provide administrative control or system-wide influence.\nThe attack flow involves: (1) Establishing a local session with low-level privileges on the target Dell SCG appliance. (2) Identifying the specific application function or interface that facilitates command invocation without adequate input validation. (3) Injecting a payload containing shell command separators (e.g., ;, &&, |) followed by malicious instructions. (4) Triggering the application process to invoke the underlying system call, leading to the execution of the injected code.\nPost-exploitation impact includes potential arbitrary file system access, lateral movement within the appliance, configuration modification, or the installation of persistent malicious backdoors to maintain long-term control.\nThe scope of the impact is constrained by the local access requirement, meaning the attacker must be capable of interacting with the local system environment, but the inherent flaw represents a critical breakdown in command string sanitization protocols."
