2008 through 2022. However, this vulnerability only affects NFSV2 and NFSV3, and Microsoft has included instructions for disabling these versions of the NFS in the bulletin.

At the same time, Microsoft characterized the ease of exploitation of these vulnerabilities as “Exploitation More Likely,” as was the case with a similar vulnerability, CVE-2021-26432, an actively exploited zero day in the TCP/IP protocol stack in Windows server that was patched in August 2021.

“Given the similarities between these vulnerabilities and those of August of 2021, we could all be in store for a rough May,” Liska noted.

The vulnerability, discovered by Akamai researcher Ben Barnea, takes advantage of three RPC runtime library flaws that Microsoft had patched in April–CVE-2022-26809, CVE-2022-24492 and CVE-2022-24528, he revealed in a blog post Tuesday. The flaws affected Windows 7, 8, 10 and 11, and Windows Servers 2008, 2012, 2019 and 2022, and could allow a remote, unauthenticated attacker to execute code on the vulnerable machine with the privileges of the RPC service.

Akamai researchers discovered that the previous patch only partially addressed the problem, allowing the new vulnerability to create the same integer overflow that was supposed to be fixed, he explained.

“During our research, we found that right before allocating memory for the new coalesced buffer, the code adds another 24 bytes to the allocation size,” Barnea wrote in the post. “These 24 bytes are the size of a struct called ‘rpcconn_request_hdr_t,’ which serves as the buffer header.” See Also: OSINT Tool: MOSINT
The previous patch performs the check for integer overflow before adding the header size, so it does not take into account this header–which can lead to the same integer overflow that the patch was attempting to mitigate, he explained.

“The new patch adds another call to validate that the addition of 24 bytes does not overflow,” mitigating the problem, Barnea wrote. Are u a security researcher? Or a company that writes articles or write ups about Cyber Security, Offensive Security (related to information security in general) that match with our specific audience and is worth sharing?

SSOh-No - User Enumeration And Password Spraying Tool For Testing Azure AD
http://www.kitploit.com/2022/05/ssoh-no-user-enumeration-and-password.html

___________________________
@hacking_Attack
@Hacking_Video

This tool is designed to enumerate users, password spray and perform brute force attacks (https://www.kitploit.com/search/label/Brute%20Force%20Attacks) against any organisation that utilises Azure AD or O365. Generally, this endpoint provides extremely verbose errors which can be leveraged to enumerate users (https://www.kitploit.com/search/label/Enumerate%20Users) and validate their passwords via brute force/spraying attacks, while also failing to log any failed authentication (https://www.kitploit.com/search/label/Authentication) attempts. This tool is a weaponised version of a PoC demonstrated in the arstechnica research article (https://arstechnica.com/information-technology/2021/09/new-azure-active-directory-password-brute-forcing-flaw-has-no-fix/%5D) which discusses the techniques utilised to exploit the endpoint. This endpoint is known to Microsoft (https://www.kitploit.com/search/label/Microsoft) however, in typical fashion it has been branded a feature, not a bug. This endpoint does enforce "smart locking" which can be bypassed by rotating IP.
Why Is This Unique? The SSO Autologon endpoint does not contain logging of any sort bar potentially updating the users "Last Logon" time. The following have been tested and contain no logs: AzureAD Sentinel Defender for Identity (Formerly Advanced Thread Protection) Defender for Cloud Apps Usage "] [-p|--password ""] [-U|--userlist ""] [-o|--outfile ""] Enumerate and abuse a sub-par Azure SSO endpoint.

hacking: security in practice
I would like to ask about the Tor network and its usefulness in a potential situation

The Philippines recently elected the son of a former dictator (Marcos) into power. If he eventually decides to try and suppress the country, could my friend in the Philippines use the Tor browser to communicate with the outside world without worrying about being censored?

What would the government be able to see? Would they be able to notice that he's connecting to the Tor network, and interrogate him for it? If so, is there any workaround for this?

What are the security benefits, caveats, and dangers of using the Onion network for this purpose?

Stepping back a bit, what are the dangers of using social media normally? I don't know if it's fake news or panic news, but apparently, police are tracking down people who were active in opposing Marcos being elected. It feels fake to me, but I'd like to ask these questions just in case it ends up being true.

My friend has been moderately active on Facebook about opposing Marcos, but not so much that I could imagine the police coming after him. There are millions of people who contributed to the extent he did. Could he be in any danger? What could he do for his safety?

I don't know much about internet security and safety, and I thought this community would. Please say if this post is not appropriate for this subreddit, and I will remove it
