CVE-2024-25713

Code Injection in github.com/ibireme/yyjson (CVE-2024-25713)

Summary

Code injection in github.com/ibireme/yyjson (CVE-2024-25713). Data can be tampered with by attackers. Exploitable via doc. Mitigation: upgrade to 0.9.0 or later.

Original description

The description as published by the source.

Summary

The pool series allocator (pool_malloc/pool_free/pool_realloc) by yysjon has a Double Free vulnerability, which may lead to arbitrary address writing and Denial of Service (DoS) attacks.
Arbitrary address writing, combined with other legitimate or illegitimate operations of programs using this library, can lead to remote code execution.

Details

The core cause of this vulnerability lies in the pool_free function's lack of loop checks, while the direct cause stems from the pool_free function and similar free-series functions not performing pointer destruction, resulting in Use-After-Free (UAF) vulnerabilities.

PoC

Below, a C language program using yyjson 0.8.0 is written to show how to exploit a Double Free vulnerability to cause chunk overlaps, which then allows the modification of a chunk's next pointer to point to an arbitrary address. If the targeted address is valid, modifications can be made. However, if the address is invalid, it could lead to the program crashing, which could be exploited for a Denial of Service (DoS) attack. Additionally, constructing a cyclic chain of chunks could force the service into an infinite loop, also exploitable for a DoS attack.

#include 
#include "yyjson.h"

char test[0x110];
int64_t a=0xffffffff;
int64_t b= (int64_t) test;

int main() {

    size_t max_json_size = 64 * 1024;

    size_t buf_size = yyjson_read_max_memory_usage(max_json_size, 0);

    void *buf = malloc(buf_size);

    yyjson_alc alc;

❓ What is the problem

Arbitrary code execution (CWE-94) exists in github.com/ibireme/yyjson. Attackers reach the vulnerable code path via doc without authentication.

📍 Affected scope

Check the vendor advisory for the affected versions of github.com/ibireme/yyjson. Attack surface: doc.

🔥 Severity

Severity: ?. Data can be tampered with by attackers.

🔧 How to fix

Update to 0.9.0.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'github.com/ibireme/yyjson' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'github.com/ibireme/yyjson' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で github.com/ibireme/yyjson を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch 
    Upgrade github.com/ibireme/yyjson to 0.9.0

    ステージング環境で 0.9.0 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
