What is Exchange Server vulnerability
Microsoft Exchange Server is vulnerable to a Server-Side Request Forgery (SSRF) vulnerability that allows attackers to send arbitrary HTTP requests and authenticate to on-premise Exchange server. Attackers can also trick the Exchange server to execute arbitrary commands by exploiting this vulnerability.
What version of Exchange is running
Start the Microsoft Exchange Management console. In the navigation pane, expand the Server Configuration objects until you locate the server object, and then select the server object. On the right side, notice the Exchange version number.
Which was responsible for Exchange Server vulnerability
Group Hafnium
March 2: Microsoft Threat Intelligence Center (MSTIC) announces Chinese Hacker Group Hafnium was responsible for the attack targeting on-premises Exchange Software.
What is CVE Mitre
Common Vulnerabilities and Exposures (CVE) is a list of publicly disclosed information security vulnerabilities and exposures. CVE was launched in 1999 by the MITRE corporation to identify and categorize vulnerabilities in software and firmware.
What is TLS Exchange
TLS basics for Microsoft 365 and Exchange Online
Transport Layer Security (TLS), and SSL that came before TLS, are cryptographic protocols that secure communication over a network by using security certificates to encrypt a connection between computers.
What version of Exchange is 365
Which Exchange version am I using
| Microsoft 365 Exchange Online and Outlook.com | 15.20.###.# |
|---|---|
| Microsoft Exchange Server 2019 CU11 | 15.2.986.5 |
| Microsoft Exchange Server 2019 CU12 | 15.2.1118.7 |
| Microsoft Exchange Server 2016 | 15.1.225.42 |
| Microsoft Exchange Server 2016 CU1 | 15.1.396.30 |
Is Exchange the same as 365
Although Exchange may be used with any email client, it is most typically used with Microsoft Outlook. Exchange is a part of Microsoft Office 365 Business Plans and Enterprise plans, the company's productivity and collaboration suite. Exchange Online plans can also be purchased separately.
What are the 2 vulnerabilities belonging to Exchange servers
ProxyNotShell is the name given to two specific Microsoft Exchange server vulnerabilities, CVE-2022-41082 and CVE-2022-41040.
Who was responsible for Exchange server
Microsoft named Hafnium as the group responsible for the 2021 Microsoft Exchange Server data breach, and alleged they were "state-sponsored and operating out of China".
Does MITRE own CVE
The CVE program is overseen by the MITRE corporation with funding from the Cybersecurity and Infrastructure Security Agency (CISA), part of the U.S. Department of Homeland Security.
Did MITRE create CVE
The CVE List was launched by the MITRE Corporation as a community effort in 1999. The U.S. National Vulnerability Database (NVD) was launched by the National Institute of Standards and Technology (NIST) in 2005.
What key exchange does TLS use
TLS key exchange allows two parties to use a cryptographic algorithm by exchanging cryptographic keys. For example, a symmetric session key is generated during SSL/TLS handshake before an encrypted message is transmitted. RSA and Diffie-Hellman-Merkle are the top key exchange algorithms used.
Does HTTPS use TLS or SSL
SSL and TLS. HTTPS today uses Transport Layer Security, or TLS. TLS is a network protocol that establishes an encrypted connection to an authenticated peer over an untrusted network. Earlier, less secure versions of this protocol were called Secure Sockets Layer, or SSL).
Is Microsoft Exchange the same as 365
Many assume that Microsoft Exchange Online and Office 365 are two different products altogether. However, this is not categorically true. Exchange Online is simply one of the many products that are included in Office 365, which is a collection of tools rather than being a single product.
Does Office 365 replace Exchange
Included in Microsoft Office 365, Exchange Online is more of a tool collection than a single product. Exchange Online usually doesn't compete with Microsoft 365 but rather complements it. Users can get one product without the other.
What are the three 3 types of network service vulnerabilities
At the broadest level, network vulnerabilities fall into three categories: hardware-based, software-based, and human-based.
What are the 4 main types of vulnerability in cyber security
The four main types of vulnerabilities in information security are network vulnerabilities, operating system vulnerabilities, process (or procedural) vulnerabilities, and human vulnerabilities.
What protocol does Exchange use
Exchange Server primarily uses a proprietary protocol called MAPI to talk to email clients, but subsequently added support for POP3, IMAP, and EAS.
How do I find the Exchange Server
Find Your Microsoft Exchange Information in Outlook for WindowsOpen Outlook and click File.Click Info, and then click Account Settings > Account Settings.Select the email account you want to connect to Inbox.Click Change.Under Server Settings, the Server field shows your Exchange server address.
Who provides CVE
the MITRE corporation
The CVE program is overseen by the MITRE corporation with funding from the Cybersecurity and Infrastructure Security Agency (CISA), part of the U.S. Department of Homeland Security.
Who controls CVE
The Mitre Corporation
The Mitre Corporation functions as Editor and Primary CNA. Various CNAs assign CVE numbers for their own products (e.g. Microsoft, Oracle, HP, Red Hat, etc.) A third-party coordinator such as CERT Coordination Center may assign CVE numbers for products not covered by other CNAs.
Who produces CVE
Founded in 1999, the CVE program is maintained by the MITRE corporation and sponsored by the U.S. Department of Homeland Security (DHS) and the Cybersecurity and Infrastructure Security Agency (CISA).
Does Exchange 365 use TLS
How Microsoft 365 uses TLS between Microsoft 365 and external, trusted partners. By default, Exchange Online always uses opportunistic TLS.
What key exchange does TLS 1.3 use
Ephemeral Elliptic-curve Diffie–Hellman
TLS recommends using ECDHE (Ephemeral Elliptic-curve Diffie–Hellman) as the key exchange algorithm. An example of suggested cipher suites is TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 . It adds a server certificate to prove its identity. Since ECDHE is selected, it puts key exchange algorithm params to the message.
Is TLS 1.2 same as HTTPS
TLS 1.2 is a protocol. HTTPS is HTTP over TLS. While TLS supports some methods to protect the connection without certificates, browsers don't – the certificate is required to make sure that the expected server is reached (i.e. protection against man in the middle attack).
