CVE-2017-11130 in StashCat
Summary
by MITRE
An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android, through 0.0.80w for Web, and through 0.0.86 for Desktop. The product's protocol only tries to ensure confidentiality. In the whole protocol, no integrity or authenticity checks are done. Therefore man-in-the-middle attackers can conduct replay attacks.

The vulnerability identified as CVE-2017-11130 affects the heinekingmedia StashCat application across multiple platforms including Android, Web, and Desktop versions. This security flaw represents a fundamental weakness in the protocol design that compromises the overall security posture of the system. The vulnerability stems from the protocol's failure to implement proper integrity and authenticity mechanisms, creating a critical gap that exposes the application to sophisticated attack vectors. The protocol's design philosophy appears to have focused exclusively on confidentiality measures while completely neglecting the essential security requirements for data integrity and source authentication.
The technical flaw manifests as the complete absence of integrity checks and authenticity verification within the communication protocol. This omission creates a scenario where attackers can intercept communications and manipulate the data flow without detection. The protocol's architecture lacks cryptographic mechanisms such as message authentication codes, digital signatures, or secure hash functions that would normally verify data integrity and authenticate the communicating parties. The vulnerability is classified as a weakness in the protocol implementation that directly violates fundamental security principles. According to CWE standards, this represents a weakness in cryptographic protocol design where proper security measures such as authentication and integrity protection are missing from the communication framework.
The operational impact of this vulnerability is severe and far-reaching, particularly for man-in-the-middle attacks that can exploit the lack of authentication and integrity checks. Attackers can conduct successful replay attacks by capturing legitimate communications and retransmitting them at a later time to gain unauthorized access or manipulate the system behavior. This vulnerability undermines the trust model of the application and allows attackers to impersonate legitimate users or systems within the network. The attack surface is particularly broad given that the vulnerability exists across multiple platform implementations, meaning that regardless of which interface a user accesses, they remain vulnerable to these attacks. The lack of proper cryptographic protection makes the system susceptible to various advanced persistent threats that can exploit this weakness over time.
The security implications extend beyond immediate exploitation to include potential long-term compromise of user data and system integrity. Since the protocol does not verify the authenticity of communications, attackers can establish false trust relationships with the application, potentially leading to unauthorized data access or modification. This vulnerability directly conflicts with established security frameworks and best practices, including those outlined in the ATT&CK framework where such weaknesses would be categorized under network protocol manipulation techniques. Organizations using this software face significant risk of data breaches, unauthorized access, and potential regulatory violations due to the lack of proper cryptographic safeguards. The vulnerability demonstrates a critical design flaw that should have been addressed during the initial security architecture phase of the application development lifecycle, highlighting the importance of implementing comprehensive security controls from the ground up rather than addressing them as afterthoughts.
