CVE-2022-20513: Information disclosure in Android
In decrypt_1_2 of CryptoPlugin.cpp, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-244569759
AI Analysis
Technical Summary
CVE-2022-20513 is a medium-severity information disclosure vulnerability found in the Android 13 operating system. The flaw exists in the decrypt_1_2 function within the CryptoPlugin.cpp source file, where a missing bounds check leads to a possible out-of-bounds read. This vulnerability is classified under CWE-125 (Out-of-bounds Read). An attacker with local privileges and limited permissions (PR:L) can exploit this vulnerability without requiring any user interaction (UI:N). The vulnerability does not allow privilege escalation or code execution but can lead to unauthorized disclosure of sensitive information stored in memory. Since the vulnerability is local and requires some privileges, it is not remotely exploitable. The CVSS v3.1 base score is 5.5, reflecting a medium severity level, with a high impact on confidentiality (C:H), but no impact on integrity (I:N) or availability (A:N). No known exploits have been reported in the wild, and no patches are explicitly linked in the provided data, although it is expected that Google would address this in subsequent Android security updates. The vulnerability affects only Android 13, which is the latest major Android release, implying that devices running this version are at risk if unpatched. The flaw could potentially expose cryptographic material or other sensitive data processed by the CryptoPlugin component, which may undermine the confidentiality guarantees of cryptographic operations on affected devices.
Potential Impact
For European organizations, the impact of CVE-2022-20513 primarily concerns confidentiality breaches on devices running Android 13. Since Android is widely used across Europe on smartphones, tablets, and embedded devices, any sensitive corporate or personal data processed on these devices could be at risk if an attacker gains local access. This includes scenarios where an attacker has physical access or has compromised a lower-privileged app or process on the device. The information disclosed could include cryptographic keys, tokens, or other sensitive data used by security-sensitive applications, potentially facilitating further attacks or data leakage. Organizations relying on Android 13 devices for secure communications, mobile workforce operations, or IoT deployments should be aware of this risk. However, the requirement for local privileges and no user interaction reduces the likelihood of widespread exploitation. The absence of integrity or availability impact means the vulnerability does not directly affect system stability or data correctness, but confidentiality breaches can have serious regulatory and reputational consequences, especially under GDPR and other European data protection laws.
Mitigation Recommendations
1. Ensure all Android 13 devices are updated promptly with the latest security patches from device manufacturers or Google, as fixes for this vulnerability are expected in official security updates. 2. Limit local access to devices by enforcing strong physical security controls and device lock policies to prevent unauthorized users from gaining local privileges. 3. Employ mobile device management (MDM) solutions to monitor device compliance and restrict installation of untrusted applications that could exploit local vulnerabilities. 4. Use application sandboxing and privilege separation to minimize the risk that a compromised app can leverage this vulnerability to access sensitive cryptographic data. 5. Conduct regular security audits and penetration testing on mobile endpoints to detect potential exploitation attempts. 6. Educate users about the risks of sideloading apps or granting unnecessary permissions, which could increase the attack surface for local exploits. 7. For high-security environments, consider additional encryption layers or hardware-backed key storage to reduce the impact of potential information disclosure at the OS level.
