Mathtype 6.8 -
MathType 6.8 has detected an unsolved equation. Synchronize?
The portal widened. Eleanor reached out—and her finger touched the screen. It didn’t stop. Her hand slipped into the cold, crisp space of corrupted LaTeX. She grabbed the floating toolbar—the classic MathType 6.8 palette—and got to work. mathtype 6.8
It was a long, ugly equation, floating in a dark, starless space. It looked like a mashup of the Riemann Hypothesis, Navier-Stokes, and a phone number from a spam email. Tentacles of mismatched brackets wrapped around its core. A single, red minus sign pulsed like a wound. MathType 6
Eleanor pulled her hand back. Her fingers smelled faintly of toner and chalk dust. Eleanor reached out—and her finger touched the screen
“What do I need to do?”
“That’s the Corrupted Conjecture ,” Epsilon Prime said, trembling. “It escaped from a cracked copy of MathType 5.0 in 1998. It’s been rewriting textbooks ever since. Last week, it made ‘2+2=5’ appear in a linear algebra textbook. The author got tenure for ‘novel arithmetic.’”
Professor Eleanor Voss, a topologist with a fondness for vintage software, had refused to upgrade for two decades. “Version 6.8 understands me,” she’d tell her graduate students, who used sleek, cloud-based equation editors. “It has soul .”
Nice write up – where can I get the vulnerable app? I checked IOLO’s website and the exploitdb but I can’t find 5.0.0.136
For “System Shield AntiVirus and AntiSpyware” you’ll need to run the downloader which downloads the main installation package but then you’ll need to also request a license. Best just to download “System Mechanic Pro” and install as a trial, this downloads the entire package and no license is required for installation

Hello.
Thanks for this demonstration!
I have a question. With this exploit, can we access to the winlogon.exe and open a handle for read and write memory?
Kind regards,
Yes you can as “SeDebugPrivilege” is also enabled
Why doesn’t it work with csrss.exe?
pHandle = OpenProcess(PROCESS_VM_READ, 0, 428); //my csrss PID
printf(“> pHandle: %d || %s\n”, pHandle, pHandle);
i got: 0 || (null)
It should work, most likely haven’t got the necessary privilege
Oh yes, thanks. But can you help me with “SeDebugPrivilege”. What offset?
Kind regards,
The SeDebugPrivilege is already enabled in this exploit, what you can do it use a previous exploit of mine which uses shellcode being injected in the winlogon process.
Thanks for nice write up. I want to study this case, so I’ve downloaded the link

And opened amp.sys file with IDA pro, but I could not find the code related to ctl code 0x00226003. How can I find it?
Best just do a text search for 226003 and only one entry will be listed
Thanks! I found with its hex byte ’03 60 22′ in IDA search and reached vulnerable function.
