CVE-2016-10611 in strider-sauce
Summary
by MITRE
strider-sauce is Sauce Labs / Selenium support for Strider. strider-sauce downloads zipped resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested zip file with an attacker controlled zip file if the attacker is on the network or positioned in between the user and the remote server.

The vulnerability identified as CVE-2016-10611 affects strider-sauce, a component that provides Sauce Labs and Selenium integration for the Strider continuous integration platform. This tool is designed to facilitate automated testing by downloading zipped resources from remote servers to execute test suites. The core security flaw stems from the application's reliance on unencrypted HTTP protocols for resource retrieval, creating a fundamental weakness in the communication channel between the client and remote servers.
The technical implementation of this vulnerability exploits the lack of secure transport mechanisms in the strider-sauce component. When the system attempts to download zipped resources, it establishes HTTP connections that are susceptible to man-in-the-middle attacks. This weakness allows attackers positioned within the network traffic path to intercept the communication and replace legitimate zip files with maliciously crafted alternatives. The vulnerability specifically relates to the absence of transport layer security measures such as TLS encryption or certificate validation, leaving the entire download process exposed to interception and modification.
The operational impact of this vulnerability extends beyond simple data interception, as it potentially enables remote code execution capabilities for attackers who successfully manipulate the download process. An attacker who can position themselves between the client and the remote server can substitute the requested zip file with a malicious archive containing harmful code. This substitution could lead to arbitrary code execution on the target system where strider-sauce is running, potentially compromising the entire continuous integration environment. The severity is amplified because the affected component operates within development environments where sensitive code and test data may be present.
This vulnerability aligns with CWE-319, which addresses the exposure of sensitive information through improper use of network protocols, and represents a classic example of insecure communication channels that can be exploited for privilege escalation and system compromise. The attack vector follows patterns consistent with MITM techniques documented in the MITRE ATT&CK framework under the T1046 category for network service scanning and T1190 for exploitation of remote services. The attack requires network position or access to manipulate traffic flow, making it particularly concerning for environments where developers work in shared or untrusted network segments. Organizations should implement secure communication protocols such as HTTPS with proper certificate validation, establish network segmentation to limit attack surface, and consider implementing network monitoring to detect unauthorized traffic manipulation attempts. The vulnerability underscores the critical importance of secure transport mechanisms in development tools and continuous integration systems that handle sensitive code and configuration data.
