Blog argues php2shell is unlikely to be mass-exploited
Original title: I want my Wednesday back
A public PoC needs four hits on one PHP worker plus the exact build, which the author says is slow to brute-force.
A blog post says php2shell is a critical flaw that should be patched quickly, especially on low-traffic sites, but argues mass exploitation within minutes is unlikely. The best PoC the author found requires four consecutive requests to the same PHP worker and knowledge of the exact PHP build, OS, and architecture. Against busy sites behind load balancers, the author estimates many connection-heavy attempts that resemble a denial of service and are likely to be noticed or blocked. The author says current in-the-wild claims refer to attempts, and HoneyLabs had not seen an attempt that could run successfully.
Unconfirmed: The author is not an exploit developer and says mass exploitation could still begin.
- The cited PoC targets a default mod_php setup of 150 workers.
- The author estimates about 50,000 build-and-worker combinations before retries.
- The localhost PoC takes 3–4 seconds; the author assumes about 10 seconds remotely.
- HoneyLabs had seen no exploit attempt that could succeed, the post says.

3 min read at blog.luitjes.itOr, why we’re not seeing mass-exploitation of php2shell yet. I saw wildly varying opinions on whether php2shell is serious, or if they cried wolf. Got curious, started digging into the PoCs.
