Description

Dell Wyse Management Suite (WMS), versions prior to 2605.0.2, contain an Improper Deserialization of Untrusted Data vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Privilege Escalation.

  "executiveSummary": "Dell Wyse Management Suite (WMS) versions prior to 2605.0.2 contain a critical Improper Deserialization of Untrusted Data vulnerability that exposes the underlying host environment to security degradation.\nThe primary impact of this flaw is local privilege escalation, potentially allowing an authenticated low-privileged actor to execute unauthorized administrative actions or compromise system integrity.\nThe affected product is Dell Wyse Management Suite across all configurations utilizing vulnerable software iterations prior to version 2605.0.2.\nThe risk implications are severe, as successful exploitation enables unauthorized elevation of privileges, breaching the principle of least privilege within the local host boundary.\nTo execute this attack, a malicious actor must possess local access to the target system coupled with low-privileged user credentials.\nNo remote network exploitation vector is directly indicated by the vulnerability characteristics, constraining the initial access requirement to local host interaction.",
  "technicalDetails": "The root cause of the vulnerability stems from the insecure handling and deserialization of untrusted data streams within the Dell Wyse Management Suite (WMS) architecture.\nImproper deserialization occurs when application logic reconstructs complex data structures from untrusted user-supplied input without adequately validating or sanitizing the serialized objects before instantiation.\nThe vulnerable component processes serialized payloads that may be manipulated by an attacker to instantiate arbitrary classes or invoke dangerous methods within the Java or application runtime environment.\nAffected versions include all iterations of Dell Wyse Management Suite preceding version 2605.0.2.\nAuthentication requirements dictate that the attacker must already possess local access to the system and authenticate as a low-privileged user to interact with the vulnerable application endpoints or IPC mechanisms.\nPrivilege requirements are constrained to low-privileged local access, which serves as the starting point for the escalation chain.\nNetwork exposure is localized, requiring the attacker to interact with the system locally rather than leveraging a remote network attack vector.\nThe attack flow begins with the low-privileged attacker identifying an input vector or interface within the Dell Wyse Management Suite that accepts serialized data objects.\nThe attacker crafts a malicious serialized payload designed to leverage gadget chains or invoke unintended functional methods upon deserialization.\nUpon submission of the crafted payload to the vulnerable component, the application parses and deserializes the untrusted data without validation.\nThe execution of the deserialization logic triggers the execution of arbitrary code or unauthorized operations within the context of a higher-privileged service or the system user.\nPost-exploitation impact culminates in local privilege escalation, granting the attacker elevated capabilities, administrative control over the application domain, or broader compromise of the underlying operating system environment."
