All versions of the package jsonpath-plus are vulnerable to Remote Code Execution (RCE) due to improper input sanitization. An attacker can execute aribitrary code on the system by exploiting the unsafe default usage of vm in Node.

Note:

There were several attempts to fix it in versions [10.0.0-10.1.0](

Impact When a special crafted packet is received via SslHandler it doesn't correctly handle validation of such a packet in all cases which can lead to a native crash.

Workarounds As workaround its possible to either disable the usage of the native SSLEngine or changing the code from:

SslContext context = ...; SslHandler handler = context.newHandler(....);

to:

SslContext context = ...; SSLEngine engine = context.newEngine(....); SslHandler handler = new SslHandler(engine, ....);

Summary An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attemps to load a file that does not exist. If an attacker creates such a large file, the Netty application crash.

Details A similar issue was previously reported in https://github.com/netty/netty/security/advisories/GHSA-xq3w-v528-46rv This issue was fixed, but the fix was incomplete in that null-bytes were not counted against the input limit.

PoC The PoC is the same as for https://github.com/netty/netty/security/advisories/GHSA-xq3w-v528-46rv with the detail that the file should only contain null-bytes; 0x00. When the null-bytes are encountered by the InputStreamReader, it will issue replacement characters in its charset decoding, which will fill up the line-buffer in the BufferedReader.readLine(), because the replacement character is not a line-break character.
