Description

Multiple vulnerabilities exist in a daemon of AOS-CX that may allow for improper processing of malformed input. An unauthenticated remote attacker could exploit these vulnerabilities by sending specially crafted packets to the affected service. Successful exploitation could result in remote code execution with elevated privileges.

  "executiveSummary": "A series of critical vulnerabilities exist within a daemon process of the AOS-CX operating system, facilitating remote code execution (RCE).\nThe core issue involves the improper processing of malformed network input, which exposes the system to memory corruption or logic errors.\nThese vulnerabilities allow an unauthenticated, remote attacker to gain elevated privileges on the target device by transmitting specially crafted packets.\nGiven the nature of the AOS-CX daemon, successful exploitation provides the attacker with full control over the compromised service, potentially leading to total system compromise.\nThe absence of authentication requirements significantly increases the risk profile, as the attack vector is accessible via the network without prior access to the management or control planes.\nImmediate attention is required to address these flaws, as they represent a high-severity threat to the confidentiality, integrity, and availability of network infrastructure managed by AOS-CX.",
  "technicalDetails": "The vulnerabilities reside within the input parsing logic of a daemon service integral to the AOS-CX operating system stack. This daemon is responsible for handling specific network-based communication protocols, and it fails to adequately validate the structure and content of incoming packets.\nThe root cause is identified as improper sanitization of input data, which likely leads to memory safety violations—such as buffer overflows or heap corruption—when processing malformed packets.\nAn unauthenticated attacker can target this service by sending crafted network packets designed to trigger these memory corruption conditions. The attack flow begins with the delivery of an oversized or syntactically invalid payload to the listening daemon. If the daemon lacks robust bounds checking or input validation routines, the malformed payload can overwrite adjacent memory segments, including control flow structures like return addresses or function pointers.\nBy controlling the instruction pointer, an attacker can redirect execution to malicious code injected within the payload or leverage Return-Oriented Programming (ROP) techniques to bypass security mitigations such as Address Space Layout Randomization (ASLR) or Data Execution Prevention (DEP).\nBecause the daemon operates with elevated system privileges, successful exploitation results in the execution of arbitrary code within that high-privilege context. This grants the attacker significant control over the AOS-CX instance, potentially allowing for the installation of persistence mechanisms, the extraction of configuration data, or the redirection of network traffic.\nThe exposure is strictly remote, meaning the device is vulnerable if the affected service is reachable from the network segment accessed by the attacker. No local user account or prior authentication is necessary to initiate the exploit, making this a critical vector for lateral movement or external infiltration of managed infrastructure."
