Description

Dell Secure Connect Gateway (SCG) Policy Manager, versions prior to 5.34.00.16, contains an Improper Check for Unusual or Exceptional Conditions vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Information tampering and Protection mechanism bypass.

  "executiveSummary": "Dell Secure Connect Gateway (SCG) Policy Manager versions prior to 5.34.00.16 are susceptible to an Improper Check for Unusual or Exceptional Conditions vulnerability, categorized under CWE-754.\nThe vulnerability resides within the Policy Manager component, potentially allowing a high-privileged, remote attacker to manipulate internal logic flows.\nSuccessful exploitation of this flaw enables information tampering and the bypass of established protection mechanisms, undermining the integrity and security posture of the gateway.\nThis vulnerability poses a significant risk to organizational infrastructure, as it facilitates unauthorized modification of policy configurations and security controls.\nExploitation requires the attacker to possess high-level administrative or system privileges and remote access to the appliance.\nOrganizations are advised to prioritize updating to the patched version, 5.34.00.16 or later, to remediate this security deficiency.",
  "technicalDetails": "The vulnerability is rooted in an 'Improper Check for Unusual or Exceptional Conditions' (CWE-754) within the Dell Secure Connect Gateway (SCG) Policy Manager. The flaw occurs when the application fails to properly validate inputs or state conditions during the execution of policy management routines. Because the system does not adequately anticipate or handle exceptional states or malformed conditions, it may proceed with operations that should otherwise be blocked or sanitized.\nThe attack flow begins with a remote attacker who has already obtained high-privileged access to the SCG environment. By intentionally triggering these exceptional conditions—likely through crafted administrative requests or state-manipulation sequences—the attacker forces the Policy Manager into an unintended execution path. This path bypasses the built-in security logic and validation checks that are designed to verify policy changes.\nFrom a technical perspective, the Policy Manager component fails to enforce strict bounds or error-handling protocols when evaluating administrative inputs. If an unusual condition is presented during a configuration update, the lack of a proper check allows for the injection or modification of policy data that violates intended system constraints. This 'fail-open' or 'fail-silent' behavior in the underlying code effectively ignores security guards, granting the attacker the ability to alter the gateway's security architecture.\nThe post-exploitation impact is severe, as it permits 'Information tampering,' enabling the attacker to rewrite security policies to weaken the target system's defenses. Additionally, the 'Protection mechanism bypass' allows the attacker to circumvent controls that would normally monitor, log, or restrict actions within the gateway. This manipulation is persistent once the altered policy is accepted by the Policy Manager, potentially exposing the environment to further unauthorized access or command execution. The absence of robust state verification ensures that these invalid states are accepted as legitimate, allowing the unauthorized configuration changes to propagate through the system's policy engine."
