Executive Summary

The vulnerability in iDS6 DSSPro Digital Signage System version 6.2 involves the cleartext transmission and storage of user authentication credentials within HTTP cookies when the autoSave ("Remember") feature is enabled. Specifically, usernames and passwords are stored in cookies without encryption, allowing remote attackers to intercept these credentials through man-in-the-middle (MITM) attacks on unencrypted HTTP communications. [1, 3, 4]

Impact Analysis

This vulnerability can lead to the exposure of sensitive user authentication credentials, including usernames and passwords, to remote attackers. By intercepting these credentials via MITM attacks on HTTP traffic, attackers can gain unauthorized access to user accounts, including administrative accounts, potentially compromising the entire digital signage system and its data.

Detection Guidance

This vulnerability can be detected by monitoring HTTP traffic for cleartext cookies that contain authentication credentials, especially when the autoSave (Remember) feature is enabled. Look for cookies named cookie.username, cookie.password, cookie.admin.username, and cookie.admin.password transmitted over unencrypted HTTP sessions. Network packet capture tools like Wireshark or tcpdump can be used to inspect HTTP requests and responses for these cookies. For example, using tcpdump to capture HTTP traffic on port 80: tcpdump -A -s 0 'tcp port 80' | grep -i 'cookie'. Additionally, inspecting web server logs or using browser developer tools to check if credentials are stored or transmitted in cookies in plaintext can help detect the issue. [1]

Mitigation Strategies

Immediate mitigation steps include disabling the autoSave (Remember) feature to prevent credentials from being stored in cookies, enforcing the use of HTTPS to encrypt all communications and prevent interception of cookies, and updating or patching the iDS6 DSSPro Digital Signage System to a version that addresses this vulnerability if available. Additionally, avoid using HTTP for accessing the system and consider implementing network-level protections such as VPNs or secure tunnels to protect traffic from man-in-the-middle attacks. [1, 4]

Compliance Impact

The vulnerability exposes user authentication credentials in cleartext cookies transmitted over HTTP, allowing attackers to intercept sensitive information via man-in-the-middle attacks. This exposure of sensitive personal data could lead to non-compliance with data protection regulations such as GDPR and HIPAA, which require the protection of personal and sensitive information during transmission. Therefore, the vulnerability poses a significant risk to compliance with these standards by failing to adequately protect user credentials and sensitive data. [1, 3, 4]
