Functions quitLock and delegate fundamentally change game theory of VoteEscrow
Lines of code Vulnerability details Impact Without delegation it is not possible to remove voting power before the end of a lock. Function quitLock now makes this possible, but it does not just affect the user who quits the lock. Any votes that are delegated to them are temporarily lost from the...
Monero: Reentrancy attack in eth-monero atomic swap
A reentrancy vulnerability was found in the eth-xmr atomic swap smart contract, allowing an attacker to drain almost all of the ethers from the smart contract. The vulnerability was fixed in a later version of the smart contract...
Conti Cybercrime Cartel Using 'BazarCall' Phishing Attacks as Initial Attack Vector
A trio of offshoots from the notorious Conti cybercrime cartel have resorted to the technique of call back phishing as an initial access vector to breach targeted networks. "Three autonomous threat groups have since adopted and independently developed their own targeted phishing tactics derived...
Microsoft Exchange Server Elevation of Privilege Vulnerability
Microsoft Exchange Server is a set of email service programs from Microsoft Corporation USA. It provides mail access, storage, forwarding, voice mail, mail filtering, etc. An elevation of privilege vulnerability exists in Microsoft Exchange Server. The vulnerability stems from an incorrect progra...
Red Hat Undertow 安全漏洞
Red Hat Undertow is a Java-based embedded web server from Red Hat, Inc. and is the default web server for Wildfly Java Application Server. Red Hat Undertow has a security vulnerability that stems from a DoS that can be realized when the Undertow server waits forever for an EJB call to LASTCHUNK...
CVE-2021-33644
An attacker who submits a crafted tar file with size in header struct being 0 may be able to trigger an calling of malloc0 for a variable gnulongname, causing an out-of-bounds read...
USN-5566-1 linux-aws, linux-aws-5.15, linux-azure, linux-azure-5.15, linux-gcp, linux-gcp-5.15, linux-gke, linux-gke-5.15, linux-ibm, linux-kvm, linux-oracle, linux-raspi vulnerabilities
Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not properly remove all references to a route filter before freeing it in some situations. A local attacker could use this to cause a denial of service system crash or execute arbitrary code...
FreeBSD -- AIO credential reference count leak
Problem Description: The aioaqueue function, used by the liolistio system call, fails to release a reference to a credential in an error case. Impact: An attacker may cause the reference count to overflow, leading to a use after free UAF...
The vulnerability of the Advanced Local Procedure Call (ALPC) handler in Windows operating systems allows attackers to enhance their privileges.
The vulnerability of the Advanced Local Procedure Call ALPC in Windows operating systems is related to deficiencies in access control. Exploiting this vulnerability can allow attackers to enhance their privileges...
[H3] Persisted msg.value in a loop of delegate calls can be used to drain ETH from your proxy
Lines of code Vulnerability details Impact msg.value in a loop can be used to drain proxy funds PoC While BoringBatchable is out of the scope, this bug affects seriously MIMOProxy as it inherits. Some time ago I read a report about an auditor called samczsung . I believe that you are having the...
Double spend in execute function from the MIMOProxy
Lines of code Vulnerability details There is batch function in MIMOProxy smart contract. The function is inherited from the BoringBatchable contract. The function accept an array of bytes - call parameters, and do delegate call to addressthis for each of the call parameters. There also is execute...
Overwriting storage slots in MIMOProxy
Lines of code Vulnerability details Impact The MIMOProxy allows you to delegate a call to another contract from a permission of owner. With a delegate call, the entire storage layout is kept the same as it is on MIMOProxy. It means that if the delegate call will be made for smart contract with...
## [H2] Multicall can be called by a malicious contract after executing a malicious delegatecall
Lines of code Vulnerability details Impact Multicall can be called though a malicious delegate call controlling all function in a vault. PoC This is related to a bug I had reported MIMOProxy can be PWNED by a malicious delegate call where I explain that storage variables can be set in delegate...
[H1] MIMOProxy can be PWNED by malicious delegate call
Lines of code Vulnerability details Impact PBR proxy owner change protection can bypassed / DoS PoC PRBProxy has a protection to prevent malicious delegatecall to overwrite owner. function executeaddress target, bytes calldata data public payable override returns bytes memory response ... ... //...
QA Report
Prevent possible future storage collisions The target action contracts of MIMOProxy.sol use storage slot 0 for immutable addresses, which doesn't currently pose an issue; however, if in future additional contracts are added which allow this slot in storage to be modified then it could open the...
Incorrect implementation of access control in MIMOProxy:execute
Lines of code Vulnerability details Description There is a function execute in MIMOProxy smart contract. The function performs a delegate call to the user-specified address with the specified data. As an access control, the function checks that either it was called by the owner or the owner has...
Unchecked Call Return Value
Lines of code Vulnerability details Impact The return value of a message call is not checked. Execution will resume even if the called contract throws an exception. If the call fails accidentally or an attacker forces the call to fail, this may cause unexpected behaviour in the subsequent program...
Delegate call can manipulate minGasReserve and the _permissions mapping.
Lines of code Vulnerability details Impact When the proxy delegatecalls the target contract the target contracts code runs in the proxy’s storage. This means the target code has access to all of proxy’s storage including internal mappings. As a result, the target contracts code can manipulate...
