Description

The Mira cloud authentication endpoints do not enforce per-account rate limiting, per-IP throttling, or account lockout after repeated failed login attempts. An attacker can use brute-force methods to obtain gain access to user accounts.

  "executiveSummary": "The identified security flaw resides within the Mira cloud authentication endpoints, which lack fundamental brute-force mitigation controls such as per-account rate limiting, per-IP throttling, and automated account lockout mechanisms following a threshold of successive failed authentication attempts.\nThis architectural omission introduces a significant risk of unauthorized access via automated credential stuffing and brute-force enumeration attacks against user accounts.\nThe affected system is the Mira cloud authentication infrastructure.\nThe risk implications are severe, as unauthorized actors can systematically compromise user accounts without encountering automated defensive roadblocks or velocity restrictions.\nAttacker capabilities include the ability to execute high-volume, automated login requests against targeted or generic user accounts utilizing credential lists.\nExploitation requirements are minimal, needing only network access to the public-facing authentication endpoints and a repository of candidate credentials to initiate systematic enumeration.",
  "technicalDetails": "The root cause of this vulnerability is the absence of protective rate-limiting logic, IP-based request throttling, and account lockout thresholds within the Mira cloud authentication endpoints.\nThe vulnerable component is the centralized authentication service handling login requests for the Mira cloud environment.\nNetwork exposure is external, as the authentication endpoints are accessible over the network to any unauthenticated client seeking to establish a session.\nAuthentication requirements for triggering the flaw are non-existent; the attacker operates without valid credentials during the initial probing and brute-force phase.\nPrivilege requirements are absent, requiring only unauthenticated network connectivity to the target login interface.\nThe exploitation method relies on automated brute-force testing, where an attacker continuously submits programmatic HTTP authentication requests containing permutations of usernames and passwords.\nThe step-by-step attack flow proceeds as follows: first, the attacker targets the Mira cloud authentication endpoints with connection probes to confirm service availability.\nSecond, the attacker deploys a multithreaded script or automated tooling to dispatch high volumes of credential pairs directly to the login interface.\nThird, because the server processes every incoming request indiscriminately without enforcing per-account rate limiting or per-IP throttling, the authentication handler evaluates each attempt sequentially or concurrently.\nFourth, the attacker monitors the HTTP response status codes, payload sizes, or response timing differentials to identify successful authentication tokens or valid session identifiers.\nFinally, once a valid credential pair is identified, the attacker leverages the obtained access to impersonate the legitimate user, leading to unauthorized resource access, data exfiltration, or subsequent post-exploitation activities within the cloud environment."
