Description

HCL AION is affected by a vulnerability where the shared storage used by product components is architected without sufficient access separation. Processes sharing the storage may be able to access or modify files beyond their intended scope, potentially resulting in unintended behavior or security impact under certain conditions.

  "executiveSummary": "HCL AION is affected by an insufficient access control vulnerability residing within its shared storage architecture. The vulnerability stems from a lack of proper access separation between product components utilizing the same shared storage repository. Consequently, processes sharing this storage layer may gain unauthorized read or write access to files and resources operating outside their intended security scope. The security implications of this architectural flaw include potential unauthorized file modification, data exposure, and subsequent unintended system behavior or compromise under specific operational conditions. Exploitation of this vulnerability requires an actor or process to possess a vantage point capable of interacting with the shared storage mechanism of the affected product. While specific authentication and privilege boundaries between interacting processes are improperly enforced by the design, the impact remains bounded by the context of the shared storage environment. Organizations deploying HCL AION face risks associated with cross-process interference and integrity violations of critical system files stored within the shared repository. No specific version numbers or external exploit requirements beyond localized process execution within the shared architecture are detailed in the baseline description.",
  "technicalDetails": "The vulnerability is fundamentally rooted in an architectural deficiency concerning storage isolation and access control enforcement within HCL AION. The product components rely on a shared storage mechanism that fails to implement rigorous security boundaries or principle of least privilege access separation between distinct executing processes. In a properly hardened multi-component system, storage partitions or file-system-level access control lists (ACLs) should strictly segregate data and executables associated with individual services. However, in this implementation, the access controls governing the shared storage repository are overly permissive.\nThe attack flow proceeds as follows: an interacting process or threat actor operating within or alongside the application environment leverages the lack of storage segmentation to traverse or target file paths outside its authorized operational perimeter. Because the shared storage layer lacks sufficient access separation, processes can directly interact with, manipulate, or exfiltrate sensitive files belonging to other isolated components of HCL AION. This unconstrained file access violates standard process containment paradigms.\nThe vulnerable component is the shared storage architecture utilized across multiple product components of HCL AION. Exploitation does not necessarily require complex network-based exploitation primitives; rather, it manifests through inter-process access capabilities where local or integrated components can transcend their security context via the file system or storage abstraction layer. The post-exploitation impact includes unauthorized modification of application files, potential code or configuration tampering, and disruption of service integrity, ultimately leading to unstable system behavior or complete compromise of the affected components depending on the nature of the modified data."
