CVE-2020-1530 and CVE-2020-1537 – Windows Remote Access Elevation of Privilege Vulnerability

Microsoft has recently released a security update for all supported operating systems. An elevation of privilege vulnerability exists when Windows Remote Access improperly handles memory.

To exploit this vulnerability, an attacker would first have to gain execution on the victim system. An attacker could then run a specially crafted application to elevate privileges.

The security update addresses the vulnerability by correcting how Windows Remote Access handles memory. A privilege elevation vulnerability (CVE-2020-1530 and CVE-2020-1537) affects all supported versions of Windows server so far.  This vulnerability exists when Windows Remote Access improperly handles memory or file operations. The exploit requires an attacker to have execution capabilities on the victim system. Systems hosting websites or with web-accessible services are particularly vulnerable.

For more information refer the following URL:

Vulnerabilities / SMF 2.0.17 Released
« on: December 31, 2019, 06:03:12 PM »
Simple Machines has released a new patch to the 2.0.x line of SMF, bringing our latest release version to 2.0.17.

We consider this patch to be of crucial importance, as it includes an important fix for a critical bug that was introduced in SMF 2.0.16.
  • Fixes a bug that could cause SMF 2.0.16 to start consuming significant amounts of CPU-resources when the RSS function was used.
  • Eliminates some deprecated function warnings when using SSI.php on PHP 7.2+.

Please see the changelog for more information.

Since SMF 2.0.17 is essentially what 2.0.16 was intended to be and 2.0.16 was released only a few days ago, we are including a (slightly updated) version of the SMF 2.0.16 announcement for your convenience:

SMF 2.0.16 contained important security and bug fixes, as well as support for the European Union's General Data Protection Regulation (GDPR) requirements. We recommend updating as soon as possible.

Notable changes in 2.0.16 & 2.0.17
  • Support for privacy policy in addition to registration agreement
  • GDPR Compliance toggle in Core Features
   Enabling this configures multiple settings and new features to comply with the GDPR, including:
  • Requiring members to accept the current privacy policy in order to use the forum
  • Asking during registration whether the new member wants to receive announcements via email
  • Enabling token-based unsubscribe links in emails so members can unsubscribe without logging in
  • Allowing members to download a copy of their profile information
  • Adjusting the behaviour of a number of other features in minor ways as necessary
  • PHP 7.2 support
  • Improved security hashes for the image proxy
  • Improved security for the login cookie
  • Assorted other security improvements
  • Various improvements for both the installer and upgrader

Vulnerabilities / SMF 2.0.16 Released
« on: December 31, 2019, 05:59:46 PM »
Simple Machines has released a new patch to the 2.0.x line of SMF, bringing our latest release version to 2.0.16.

We consider this patch to be of crucial importance, as it includes important security and bug fixes, as well as support for the European Union's General Data Protection Regulation (GDPR) requirements. We recommend updating as soon as possible.

  • PHP 7.2 support
  • Improved security hashes for the image proxy
  • Improved security for the login cookie
  • Assorted other security improvements
  • Various improvements for both the installer and upgrader
Please see the changelog for more information.


IMPORTANT NOTES:
  • If you are using the GDPR Helper mod, you should follow these steps:
  • Back up your existing privacy policy text to a file somewhere
  • Update the GDPR Helper mod to its latest version
  • Uninstall the GDPR Helper mod
  • Install the SMF 2.0.16 patch

All users, including the admin, will need to log in again after 2.0.16 has been installed.

How to update to 2.0.16

If you are running version 2.0.15, you can update your forum to the latest version by using the package manager. You should see the update notification in the admin panel notifications and in the package manager, which will allow you to download and install the patch seamlessly.  If you do not see the notification about the patch, please run the scheduled task "Fetch Simple Machines files" from the Scheduled Tasks page (Admin > Maintenance > Scheduled Tasks).

If you use older versions of SMF, you can upgrade directly to 2.0.15 from whichever version you are currently using by using the "Large Upgrade" package from the Download page. Be aware that using this upgrade method will require you to reinstall any customizations that you have added to your forum, so if you are running a version of the 2.0.x series, it is recommended that you apply the successive patches instead of using the Large Upgrade.

If you are having problems downloading the patch from the admin panel, you can download the patch package from the Package Manager Updates page and install it via the Package Manager, as you would any other mod package.

Please refer to the Online Manual for more details about patching and upgrading.

cPanel/WHM / WHMCS Enom error - CURL Error: 56 - OpenSSL SSL_read: Success
« on: November 22, 2019, 12:10:26 PM »
After upgrade to CURL version 7.67.0, you may receive the following error:

CURL Error: 56 - OpenSSL SSL_read: Success

Usually WHMCS and Enom users are reporting the above error. If you are using cPanel, you can downgrade the CURL version to fix this. You can execute following command on a cPanel server to downgrade the version:

yum downgrade ea-libcurl ea-libcurl-devel

Make sure that you restart Apache service. Also, if you are using litespeed, Apache-fpm, nginx etc., make sure you restart those services as well.

Notification from cPanel:

------------------

Today we are excited to announce that we're shifting to an account based pricing and licensing structure and to share what that means for your relationship with cPanel. We aim to simplify the process of adding new servers, make it easier to become a cPanel customer, and provide value to a broader group of users.
Introducing Account Based Pricing

The hosting industry has changed a lot in the last 20 years, and has long out-grown the licensing and pricing structure that we have used at cPanel. Effective immediately, cPanel's license structure and the way we price our products is changing. Our pricing and licensing structure will now be standardized for all of our customers and include multiple Tiers. This new structure defines the price of each license based on the number of Accounts hosted on the server, reflecting the value received by the owner; now, customers pay for only what they use. On September 1st, 2019, we will introduce Auto-Scaling Packages, Fixed Packages, and transition all existing monthly licenses to the new account based pricing and licensing structure.
-------------------------------------------------
There will be no unlimited domains license now and pricing will be affected to all providers who are offering unlimited domains hosting. Now, you will have to pay $$$ instead of few bucks for cPanel license and most of the providers are now already started looking for the alternative.

New pricing are mentioned on their website:

TCP SACK PANIC - Kernel vulnerabilities - CVE-2019-11477, CVE-2019-11478 & CVE-2019-11479

A vulnerability targeting the networking stack in linux servers running kernel 2.6.29 or newer has been discovered that allows for Networking denial-of-service of varying severity, leveraging TCP "Selective Acknowlegment" (SACK).

Because the vulnerability requires absolutely no authentication, it could be used to deny networking indefinitely to any linux server using an unpatched kernel released in the last 10 years.

You can read more about the exploit (and patches mitigating it), here: https://www.openwall.com/lists/oss-security/2019/06/17/5 and here https://access.redhat.com/security/vulnerabilities/tcpsack

Centos 5 hosts and older cannot be updated due to lack of support, so it requires disabling SACK on them.
