Two WordPress plugins, InfiniteWP Client and WP Time Capsule have been found to suffer from a critical authorization bypass bug that allows people to access a site’s backend with no password. All an attacker needs is the admin username for the WordPress plugins and they are in.
Both plugins are designed to allow users to authenticate to multiple WordPress installations from one central server. That allows site owners to “perform maintenance such as one-click updates for core, plugins, and themes across all sites, backup and site restores, and activating/deactivating plugins and themes on multiple sites simultaneously".
This was reported on January 7th and on January 8th a new release for InfiniteWP Client and WP Time Capsule was released. WebArx publicly disclosed the bugs on January 14th.
Based on the WordPress plugin library, the InfiniteWP Client plugin is active on 300,000+ websites. The InfiniteWP site claims they have 513,520 sites active.

On January 14, 2020, Microsoft released software fixes to address 49 vulnerabilities as part of their monthly Patch Tuesday announcement. Among the vulnerabilities patched were critical weaknesses in Windows CryptoAPI, Windows Remote Desktop Gateway (RD Gateway), and Windows Remote Desktop Client. An attacker could remotely exploit these vulnerabilities to decrypt, modify, or inject data on user connections:
The updates fixes a serious flaw in the core cryptographic component of widely used Windows 10, Server 2016 and 2019 editions that was discovered and reported to the company by the National Security Agency (NSA) of the United States
The flaw, dubbed 'NSACrypt' and tracked as CVE-2020-0601, resides in the Crypt32.dll module that contains various 'Certificate and Cryptographic Messaging functions' used by the Windows Crypto API for handling encryption and decryption of data.
A cyber attacker could exploit CVE-2020-0601 to obtain sensitive information, such as financial information, or run malware on a targeted system; for example:
A maliciously crafted certificate could appear to be issued for a hostname that did not authorize it, preventing a browser that relies on Windows CryptoAPI from validating its authenticity and issuing warnings. If the certificate impersonates a user’s bank website, their financial information could be exposed. Signed malware can bypass protections (e.g., antivirus) that only run applications with valid signatures. Malicious files, emails, and executables can appear legitimate to unpatched users.
Besides Windows CryptoAPI spoofing vulnerability that has been rated 'important' in severity, Microsoft has also patched 48 other vulnerabilities, 8 of which are critical and rest all 40 are important.
It is strongly suggested that you patch this as soon as possible by heading on to your Windows Settings → Update & Security → Windows Update → clicking 'Check for updates on your PC.

Pulse Secure, a provider of secure VPN, urged customers today to immediately apply a security patch if they have not yet done so. The advice comes from reports over the last few days of attackers exploiting a flaw to deliver ransomware on enterprise systems. It can even be used to delete data backups and disable endpoint security tools.
This flaw has been present for some time and Kevin Beaumont who first reported the attacks this weekend have outlined its backstory since it was discovered in April 2019. It is believed that it was this flaw that was used to attack travel insurance and currency exchange provider Travelex, which experienced a massive service disruption this week following a reported ransomware attack on its systems on New Year's Eve.
This flaw, that exists in multiple versions of Pulse Connect Secure and Pulse Policy Secure, gives remote attackers a way to connect via HTTPS to an enterprise network without needing any valid username or password. Attackers can use the flaw to view logs and files, turn-off multifactor authentication, download arbitrary files, and execute malicious code on enterprise networks.The attacker can also see cached passwords in plain text, including Active Directory account passwords.
According to threat intelligence firm Bad Packets, at least 3,825 Pulse Secure VPN servers remain unpatched and vulnerable to attack as of January 3, 2020. More than 1,300 of the vulnerable systems are located in the United States. According to Kevin Beaumont, Travelex had seven unpatched Pulse Secure servers when it was attacked on New Year's Eve.
It is strongly suggested that if you use Pulse Connect Secure or Pulse Policy Secure that you take this seriously and ensure that you have applied all the latest patches. Ransomeware like Sodinokibi, also known as REvil, is no joke and it can cripple or even destroy companies it affects.
