Loading vulnerability…
CVE-2022-35737 is an array-bounds overflow in SQLite versions 1.0.12 through 3.39.x before 3.39.2. The flaw can be triggered when a string argument containing billions of bytes is supplied to a SQLite C API, causing an array-bounds overflow.

This repository provides proof-of-concept (PoC) exploits for CVE-2022-35737, an integer overflow vulnerability in the SQLite3 library's sqlite3_str_vappendf function. The vulnerability affects SQLite versions 3.31.1 through 3.39.1 on 64-bit systems. The repository includes several C programs and a PHP script: - 'snprintf-good-example.c' demonstrates normal, safe usage of sqlite3_snprintf. - 'snprintf-crash.c' triggers a segmentation fault by passing a very large string, demonstrating a denial-of-service condition. - 'snprintf-control-pc.c' crafts a payload to overwrite the stack canary and saved return address, showing the potential for arbitrary code execution if stack canaries are not present. - 'snprintf-livelock.c' causes the vulnerable function to enter an endless loop, demonstrating another form of denial-of-service. - 'pdo-sqlite3-quote-poc.php' shows that the vulnerability is reachable from PHP via the PDO SQLite driver, resulting in a crash when run with a high memory limit. A Dockerfile is provided to build a container with the vulnerable version of SQLite and all dependencies, and a Makefile is included to compile the C PoCs. The main exploit vector is local: an attacker must be able to supply large, crafted input to a program using the vulnerable SQLite version. The only fingerprintable endpoint is the local SQLite database file used in the PHP PoC. The repository is structured as a set of PoCs for research and demonstration purposes, not as a weaponized exploit.
