Link to public exploit:

Vulnerability description

The vulnerability allows a remote authenticated attacker to cause DoS condition or execute arbitrary code.

The vulnerability exists due to improper handling of certain stream encodings by the zgfx_decompress_segment() function, as defined in the zgfx.c source code file. A remote attacker can send a specially crafted request that submits malicious input, trigger a heap-based buffer overflow condition that the attacker can use to cause a DoS condition or execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.
