I guess this lets us reset the program if things don't go our way. If we have some kind of UAF (Use-After-Free) or heap corruption situation going on, this will probably cause a segmentation fault or abort infree(). After a brief audit of the source code, we can see that the pr...
由于低版本(<5.16)内核中缺少了[补丁](https://github.com/torvalds/linux/commit/ed0a0c60f0e50fa52853620672af97edde3d3a03),导致无法使用`nft_quota`结构体的`consumed`字段来写读写内存地址,考虑使用rop的方法进行提权。google的exp里使用了`NFT_MSG_DELRULE+NFT_MSG_DELSET`的方法来触发uaf,但是实际测试中...
Exploit for Use After Free in Microsoft CVE-2024-43582 | Sploitus | Exploit & Hacktool Search Engine
This functionality opens some interesting ways trigger a Use-After-Free. First the pointer to the gstring struct is stored at a static variable, thismeans on future calls to tls_write() we will be able to use it. How can we free the buffer and then be able to use it? We need...
We can use the following command: objdump -R ../../challenge/pet_companion | grep -i write This is the final code for this part, you may notice that I pop a junk value after the GOT write one, this is because the gadget that I’ve found will pop something else in another ...

FUZE: Towards Facilitating Exploit Generation for Kernel Use-After-Free Vulnerabilities 作者:中科院 吴炜、宾夕法尼亚州立大学 陈越琦 会议:Usenix 2018 开源地址:github.com/ww9210/Linux论文背景:软件供应商通常根据其利用的难易程度来确定其缺陷补救的优先顺序。但是准确确定可利用性通常需要花费大量的时间,并且需...
而我们一般所指的 Use After Free 漏洞主要是后两种。此外,我们一般称被释放后没有被设置为 NULL 的内存指针为 dangling pointer。类比Linux的内存管理机制,Windows下的内存申请也是有规律的,我们知道ExAllocatePoolWithTag函数中申请的内存并不是胡乱申请的,操作系统会选择当前大小最合适的空闲堆来存放它。如果你足够细心...
如果你是一个pwn选手,那么肯定很清楚UAF的原理,简单的说,Use After Free 就是其字面所表达的意思,当一个内存块被释放之后再次被使用。但是其实这里有以下几种情况: 而我们一般所指的 Use After Free 漏洞主要是后两种。此外,我们一般称被释放后没有被设置为 NULL 的内存指针为 dangling pointer。类比Linux的内存...
To test the theory we can use the following loop (on a 1.2gb mapped section) to find 'Proc' pool chunks and dump out some EPROCESS data for confirmation.? echo "`n[>] Parsing physical memory, coffee time..`n" for ($i=0x30000000;$i -lt $(1200*1024*1024); $i+=0x10) { # Re...
