CVE-2017-12824 is an arbitrary code execution vulnerability in InPage, a word processing and publishing application used for Urdu and Arabic content. The flaw is in the parsing logic of the proprietary document format, specifically handling of the InPage100 stream in inpage.exe. Available analysis indicates InPage fails to properly validate certain type values while processing document fields, resulting in an out-of-bounds read that can be leveraged to reach an out-of-bounds function pointer access. By crafting a malicious .inp document with attacker-controlled field values, an attacker can redirect instruction flow to embedded shellcode. In observed exploitation, the malicious document contained staged shellcode that located and decoded additional payload components and then downloaded and executed malware. The issue was reported as a zero-day and assigned CVE-2017-12824.
