https-proxy-agent is a valuable Node.js package for developers working with HTTPS and proxy servers. Version 0.3.1, released on November 16, 2013, is a minor update to the previous stable version 0.3.0, released on September 16, 2013. Both versions offer an http.Agent implementation specifically designed for routing HTTPS requests through an HTTP(s) proxy, crucial in environments requiring proxy usage for network access.
The core functionality and dependencies remain consistent between both versions. Developers can expect the same robust performance leveraging the debug, extend, and agent-base dependencies for debugging, object extension, and base agent functionality, respectively. Development dependencies, including mocha for testing, proxy for proxy server emulation, and semver for version management, also remain unchanged.
The significance of version 0.3.1 lies in potential bug fixes or minor improvements not explicitly documented in the provided metadata. While the API and core features appear identical to version 0.3.0, users are encouraged to upgrade to the latest minor version (0.3.1) to benefit from any stability enhancements or security patches. For developers relying on proxy configurations in their HTTPS applications, https-proxy-agent simplifies the process, and using the more current minor version ensures access to the most refined and reliable implementation available at the time.
All the vulnerabilities related to the version 0.3.1 of the package
Denial of Service in https-proxy-agent
Versions of https-proxy-agent before 2.2.0 are vulnerable to denial of service. This is due to unsanitized options (proxy.auth) being passed to Buffer().
Update to version 2.2.0 or later.
Machine-In-The-Middle in https-proxy-agent
Versions of https-proxy-agent prior to 2.2.3 are vulnerable to Machine-In-The-Middle. The package fails to enforce TLS on the socket if the proxy server responds the to the request with a HTTP status different than 200. This allows an attacker with access to the proxy server to intercept unencrypted communications, which may include sensitive information such as credentials.
Upgrade to version 3.0.0 or 2.2.3.
debug Inefficient Regular Expression Complexity vulnerability
A vulnerability classified as problematic has been found in debug-js debug up to 3.0.x. This affects the function useColors of the file src/node.js. The manipulation of the argument str leads to inefficient regular expression complexity. Upgrading to version 3.1.0 is able to address this issue. The name of the patch is c38a0166c266a679c8de012d4eaccec3f944e685. It is recommended to upgrade the affected component. The identifier VDB-217665 was assigned to this vulnerability. The patch has been backported to the 2.6.x branch in version 2.6.9.
Regular Expression Denial of Service in debug
Affected versions of debug are vulnerable to regular expression denial of service when untrusted user input is passed into the o formatter.
As it takes 50,000 characters to block the event loop for 2 seconds, this issue is a low severity issue.
This was later re-introduced in version v3.2.0, and then repatched in versions 3.2.7 and 4.3.1.
Version 2.x.x: Update to version 2.6.9 or later. Version 3.1.x: Update to version 3.1.0 or later. Version 3.2.x: Update to version 3.2.7 or later. Version 4.x.x: Update to version 4.3.1 or later.
Prototype Pollution in extend
Versions of extend prior to 3.0.2 (for 3.x) and 2.0.2 (for 2.x) are vulnerable to Prototype Pollution. The extend() function allows attackers to modify the prototype of Object causing the addition or modification of an existing property that will exist on all objects.
If you're using extend 3.x upgrade to 3.0.2 or later.
If you're using extend 2.x upgrade to 2.0.2 or later.
