BIT-vault-2025-6014
Code Reuse vulnerability in vault (Go)
What is BIT-vault-2025-6014 About?
HashiCorp Vault's TOTP Secrets Engine is susceptible to a code reuse vulnerability. This could potentially allow an attacker to bypass intended security controls by subtly reusing existing code paths in an unintended way. The impact could be unauthorized access or privilege escalation. Exploitation details are not explicitly described but often involve intricate understanding of the internal logic.
Affected Software
Technical Details
The Hashicorp Vault's TOTP Secrets Engine contains a code reuse vulnerability. While the exact mechanism is not detailed, such vulnerabilities typically involve an attacker leveraging legitimate code paths or functions within the software, but in an unintended sequence or context, to achieve a malicious outcome. This could entail manipulating input or state to trigger a specific code execution flow that circumvents security checks that would normally be in place. For instance, it might involve using a function designed for one purpose to validate or process data in a way that leads to a bypass of the TOTP authentication logic, or to gain unauthorized access to secrets managed by the engine without proper TOTP validation.
What is the Impact of BIT-vault-2025-6014?
Successful exploitation may allow attackers to bypass the TOTP authentication mechanism, leading to unauthorized access to secrets managed by the TOTP Secrets Engine, potentially comprising sensitive data.
What is the Exploitability of BIT-vault-2025-6014?
Exploitation complexity is likely high, as code reuse vulnerabilities often require a deep understanding of the application's internal structure and execution flow. Prerequisites would likely involve being an authenticated user of Vault who can interact with the TOTP Secrets Engine, or identifying specific API endpoints vulnerable to such manipulation. Authentication to Vault is a requirement. Privilege requirements might be standard user privileges, which are then escalated or misused through the vulnerability. Access could be remote, as Vault is a network service. Special conditions are not explicitly detailed but would involve carefully crafted requests or sequences of actions to trigger the unintended code reuse. The likelihood of exploitation is generally low due to the intricate knowledge required to identify and leverage such a subtle flaw.
