Description

Dell ThinOS 10, versions prior to 2605_10.2518, contain an Improper Access Control vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Unauthorized access.

  "executiveSummary": "Dell ThinOS versions prior to 2605_10.2518 suffer from an Improper Access Control vulnerability, posing a localized security risk to enterprise environments utilizing the operating system.\nThe vulnerability class is classified as improper access control, which fundamentally allows unauthorized subjects to interact with system resources or components that should otherwise be restricted based on privilege levels.\nThe primary impact of successful exploitation is unauthorized access to sensitive system functions, data, or operational capabilities managed by the thin client OS.\nThe affected product is Dell ThinOS 10, specifically all deployments running firmware or software versions preceding 2605_10.2518.\nRisk implications include potential privilege escalation, unauthorized manipulation of system configurations, or exposure of sensitive data stored or processed within the local thin client environment.\nThe required attacker capabilities are strictly low-privileged, meaning an adversary requires an existing execution context or standard user account on the local operating system.\nExploitation requirements dictate that the attacker must possess local access to the target endpoint running the vulnerable Dell ThinOS version, as remote exploitation vectors are not detailed or implied by the access control flaw.",
  "technicalDetails": "The root cause of the vulnerability stems from insufficient access control enforcement within the Dell ThinOS 10 architecture prior to version 2605_10.2518.\nSpecifically, internal system components, APIs, or operational interfaces fail to adequately validate the execution context and authorization boundaries of incoming requests originating from low-privileged user sessions.\nThe vulnerable component involves local authorization and privilege separation mechanisms governing interactions between low-privileged users and protected system operations.\nAffected versions encompass all instances of Dell ThinOS 10 released prior to the patched iteration 2605_10.2518.\nAuthentication requirements are minimal; the attacker must already be authenticated locally to the operating system with low privileges.\nPrivilege requirements are explicitly low-privileged, indicating that unprivileged or standard local users can bypass intended security boundaries without requiring administrator or root credentials.\nNetwork exposure is local, meaning the attack surface is restricted to the physical or logical console of the device, eliminating direct remote network attack vectors.\nThe attack flow begins with the low-privileged attacker establishing a local session on the target Dell ThinOS 10 endpoint.\nLeveraging the improper access control flaw, the attacker interacts with the vulnerable component, submitting requests or invoking functions that bypass standard security gating.\nBecause access control checks are absent or incorrectly implemented, the system processes the unauthorized request as valid.\nPost-exploitation impact includes the potential attainment of unauthorized access, allowing the low-privileged user to execute privileged actions, access restricted resources, or compromise the integrity and confidentiality of the thin client environment."
