AI-analyzed exploit summary This repository contains a functional exploit PoC for CVE-2026-25243, which targets an invalid memory access vulnerability in the Redis RESTORE command. The exploit leverages a crafted payload to trigger a heap-based buffer overflow, potentially leading to remote code execution.
Description
Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This is patched in version 8.6.3.
Exploits (6)
This repository contains a functional exploit PoC for CVE-2026-25243, which targets an invalid memory access vulnerability in the Redis RESTORE command. The exploit leverages a crafted payload to trigger a heap-based buffer overflow, potentially leading to remote code execution.
This repository contains a comprehensive exploit chain for CVE-2026-25243, a heap-based vulnerability in Valkey/Redis involving a zipmap parsing flaw. The PoCs demonstrate a heap over-read, double-free, type confusion, and full remote code execution (RCE) with ASLR/PIE bypass, including self-calibrating leaks and PIE-relative ROP chains.
This repository contains a functional exploit for CVE-2026-25243, a Redis RESTORE zipmap double-free vulnerability leading to unauthenticated remote code execution (RCE) without requiring the DEBUG command. The exploit leverages jemalloc heap manipulation to achieve type confusion and arbitrary read/write primitives, culminating in command execution as the Redis process.
The repository contains a functional exploit PoC for CVE-2026-25243, demonstrating an invalid memory access vulnerability in the Redis RESTORE command that can lead to remote code execution. The exploit uses a crafted payload to trigger a heap-based buffer overflow, with detailed instructions and code to reproduce the issue.
