CVE-2022-41209 is a medium-severity vulnerability identified in version 7.4 of SAP Customer Data Cloud (Gigya) mobile application for Android. The core issue stems from the use of an encryption method that lacks proper diffusion, meaning that the encryption does not sufficiently obscure patterns in the plaintext data. This weakness can lead to information disclosure, as attackers analyzing encrypted data might infer sensitive information by recognizing repeated patterns or structures. Additionally, the application may be vulnerable to replay attacks under certain conditions, where an attacker intercepts and retransmits valid data transmissions to gain unauthorized access or cause unintended effects. The vulnerability is categorized under CWE-326, which relates to the use of weak cryptographic primitives or improper cryptographic implementations. The CVSS v3.1 base score is 5.2, reflecting a medium severity level, with the vector indicating that the attack requires physical proximity (AV:P), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts confidentiality highly (C:H), integrity to a lesser extent (I:L), and does not affect availability (A:N). No known exploits are currently reported in the wild, and no patches have been explicitly linked in the provided information. The vulnerability could allow attackers with network access to the device to extract sensitive customer data or manipulate authentication flows, potentially undermining user privacy and trust in the affected applications.

For European organizations using SAP Customer Data Cloud (Gigya) version 7.4 on Android devices, this vulnerability poses a risk of sensitive customer data exposure due to weak encryption. Given the GDPR and other stringent data protection regulations in Europe, any leakage of personal data can lead to significant legal and financial repercussions, including fines and reputational damage. Replay attacks could also allow unauthorized access or manipulation of user sessions, potentially leading to fraud or unauthorized transactions. Organizations relying on Gigya for customer identity and access management may face disruptions in trust and service integrity. The impact is particularly critical for sectors handling sensitive personal data such as finance, healthcare, and e-commerce. Since the attack vector requires physical proximity (e.g., local network access), organizations with employees or customers in public or semi-public environments (e.g., retail stores, events) may be more vulnerable. The lack of known exploits reduces immediate risk but does not eliminate the potential for targeted attacks, especially from sophisticated threat actors.

To mitigate this vulnerability, European organizations should prioritize upgrading or patching SAP Customer Data Cloud (Gigya) to a version where the encryption implementation is corrected, once such a patch is available from SAP. In the interim, organizations should enforce network segmentation and restrict access to mobile devices running the affected version, especially on untrusted or public networks, to reduce the risk of local network attacks. Employing VPNs or secure tunnels for mobile app communications can help protect data in transit. Monitoring network traffic for unusual replay patterns or repeated requests can aid in early detection of exploitation attempts. Additionally, organizations should review and strengthen their cryptographic policies, ensuring that all cryptographic operations use well-vetted, standard algorithms with proper implementation. User awareness campaigns to avoid connecting to untrusted Wi-Fi networks and enforcing device security policies (e.g., disabling unnecessary wireless interfaces) can further reduce exposure. Finally, organizations should maintain robust incident response plans tailored to data leakage and replay attack scenarios.
