Open Source Social Network < 5.3 - Arbitrary File Read via Weak PRNG in SiteKey
Title source: llmExploitation Summary
EIP tracks 3 public exploits for CVE-2020-10560. PoCs published by kevthehermit, alex-seymour.
AI-analyzed exploit summary This repository contains a working PoC for CVE-2020-10560, an arbitrary file read vulnerability in Open Source Social Network (OSSN). The exploit leverages weak encryption in the `comment/staticimage` endpoint to read arbitrary files by crafting malicious requests.
Description
An issue was discovered in Open Source Social Network (OSSN) through 5.3. A user-controlled file path with a weak cryptographic rand() can be used to read any file with the permissions of the webserver. This can lead to further compromise. The attacker must conduct a brute-force attack against the SiteKey to insert into a crafted URL for components/OssnComments/ossn_com.php and/or libraries/ossn.lib.upgrade.php.

This repository contains a working PoC for CVE-2020-10560, an arbitrary file read vulnerability in Open Source Social Network (OSSN). The exploit leverages weak encryption in the `comment/staticimage` endpoint to read arbitrary files by crafting malicious requests.
This repository contains a proof-of-concept for CVE-2020-10560, which exploits an arbitrary file read vulnerability in OSSN (Open Source Social Network) to recover the site_key used for AES encryption. The PoC includes utilities for base64 encoding/decoding and AES operations to facilitate key recovery.
This repository contains a functional PoC for CVE-2020-10560, which recovers the `site_key` for Open Source Social Network (OSSN) 5.3 and above. The exploit leverages an arbitrary file read vulnerability to extract the AES-encrypted key and decrypt it using included libraries (base64 and tiny-AES-c).
