CVE-2025-2394 identifies a vulnerability in the Ecovacs Home mobile applications for Android and iOS, specifically up to version 3.3.0. The core issue is the presence of hard-coded credentials embedded within the application code. These credentials are access keys and secrets for Alibaba Object Storage Service (OSS), a cloud storage platform. Hard-coded credentials represent a significant security flaw (CWE-798) because they can be extracted by attackers through reverse engineering or static analysis of the application binaries. Once obtained, these credentials provide unauthorized access to the associated OSS resources, potentially exposing sensitive data stored in the cloud. The vulnerability does not require user interaction, privileges, or network access beyond local access to the app, but exploitation requires the attacker to analyze the app package or memory to extract the keys. The CVSS 4.0 vector indicates the attack vector is physical (AV:P), with low attack complexity (AC:L), no privileges or authentication required (PR:N, AT:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is low to limited (VC:L, VI:L, VA:L), but the scope is high (SC:H) and the impact on security requirements is high (SI:H, SA:H), reflecting the potential for significant data exposure and misuse of cloud resources. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability highlights the risk of embedding static secrets in mobile applications, which can lead to unauthorized data disclosure and cloud resource compromise.

For European organizations using Ecovacs Home applications, this vulnerability could lead to unauthorized access to sensitive data stored in Alibaba OSS buckets linked to the app. This may include user data, device telemetry, or other confidential information managed by the app. The exposure risks data confidentiality breaches, potential privacy violations under GDPR, and reputational damage. Additionally, attackers could manipulate or delete data, impacting data integrity and availability. Although the CVSS score is medium, the high scope and security impact ratings suggest that the consequences could be significant if exploited. Organizations relying on Ecovacs devices for smart home automation or business environments may face operational disruptions or data leakage. The lack of required authentication or user interaction lowers the barrier for exploitation once the credentials are extracted. Given the cross-platform nature of the app (Android and iOS), a wide user base across Europe could be affected. The vulnerability also raises concerns about supply chain security and the need for secure credential management in IoT and mobile ecosystems.

Immediate mitigation steps include: 1) Updating to a fixed version of the Ecovacs Home app once released that removes hard-coded credentials and implements secure credential storage mechanisms such as dynamic retrieval via secure APIs or use of encrypted keystores. 2) Organizations should monitor network traffic for unusual access patterns to Alibaba OSS resources associated with Ecovacs to detect potential unauthorized access. 3) Rotate and revoke any exposed Alibaba OSS credentials linked to the app to prevent misuse. 4) Employ mobile application security testing and reverse engineering detection to identify and block tampering attempts. 5) Educate users and administrators about the risks of using outdated app versions and encourage timely updates. 6) For organizations integrating Ecovacs devices, implement network segmentation and strict access controls to limit potential lateral movement if the vulnerability is exploited. 7) Engage with Ecovacs support to obtain timelines for patches and request transparency on remediation efforts. These steps go beyond generic advice by focusing on credential rotation, active monitoring of cloud resources, and secure app update practices.
