  • The exploit delivers a SWF file via HTTP with Content-Type 'application/x-shockwave-flash' and a 'Pragma: no-cache' header; detect HTTP responses serving .swf files with this header combination in browser exploit context.
  • The exploit targets Adobe Flash Player version exactly 16.0.0.235 on Windows 7 via Internet Explorer; detections should flag this specific Flash version loading SWF content from untrusted sources.
  • The exploit HTML template embeds a SWF with 'allowScriptAccess=always' and passes a base64-encoded PowerShell payload via the FlashVars 'sh' parameter; monitor for Flash objects with these attributes in HTML.
  • The vulnerability is a PCRE compilation logic error in the handling of the \c escape sequence followed by a multi-byte UTF8 character, enabling arbitrary PCRE bytecode execution inside Flash; inspect SWF files for malformed PCRE regex patterns with \c followed by multi-byte UTF8.
  • The Metasploit module uses a randomly named .swf file (rand_text_alpha) served from the same exploit URI; look for HTML pages that embed a dynamically named .swf alongside base64-encoded FlashVars content.
  • ·The Metasploit module explicitly restricts exploitation to Flash version 16.0.0.235 only, though other versions are noted as vulnerable; broader version coverage requires additional validation.
  • ·The module targets Windows 7 with Internet Explorer exclusively; other OS/browser combinations (including Linux and OS X) are listed as vulnerable in the CVE but are not covered by this exploit module.
  • ·The payload space is limited to 1024 bytes with NOP insertion disabled; staged or larger payloads may not function correctly with this exploit.
