Cybercriminals Privileging From Covid-19. Critical Bugs Found in Three Popular e-Learning Plugins for WordPress Sites.

By Editor


          WordPress Online Learning Plugin.

Security researchers are sounding the alarm over newly discovered vulnerabilities in some popular online learning management system (LMS) plugins that various organizations and universities use to offer online training courses through their WordPress-based websites.
According to the Check Point Research Team, the three WordPress plugins in question — LearnPress, LearnDash, and LifterLMS — have security flaws that could permit students, as well as unauthenticated users, to pilfer personal information of registered users and even attain teacher privileges.
"Because of coronavirus, we're doing everything from our homes, including our formal learning," Check Point Research's Omri Herscovici said. "The vulnerabilities found allow students, and sometimes even unauthenticated users, to gain sensitive information or take control of the LMS platforms."

The three LMS systems are installed on approximately 100,000 different educational platforms, including major universities such as the University of Florida, the University of Michigan, and the University of Washington, among others.
LearnPress and LifterLMS alone have been downloaded over 1.6 million times since their launch.
Multiple Vulnerabilities in WordPress LMS Plugins
LMS facilitates online learning via a software application that lets academic institutions and employers create course curriculum, share coursework, enroll students, and evaluate students with quizzes.
Plugins such as LearnPress, LearnDash, and LifterLMS make it easy by adapting any WordPress site to a fully functioning and easy-to-use LMS.


The flaws in LearnPress range from blind SQL injection (CVE-2020-6010) to privilege escalation (CVE-2020-11511), which can authorize an existing user to gain a teacher's role.
"Unexpectedly, the code doesn't check the permissions of the requesting user, therefore letting any student call this function," the researchers stated.
LearnDash, likewise, suffers from a SQL injection flaw (CVE-2020-6009) that allows an adversary to craft a malicious SQL query by using PayPal's Instant Payment Notification (IPN) message service simulator to trigger fake course enrollment transactions.

Lastly, LifterLMS's arbitrary file write vulnerability (CVE-2020-6008) exploits the dynamic nature of PHP applications to allow an attacker, e.g., a student registered for a specific course, to change their profile name to a malicious piece of PHP code.
In total, the flaws make it possible for attackers to steal personal information (names, emails, usernames, passwords, etc…), and students to change grades, retrieve tests and test answers beforehand, and also forge certificates.
"The platforms involve payment; therefore, financial schemes are also applicable in the case of modifying the website without webmaster's information," the researchers warned.
Check Point Research said the vulnerabilities were discovered in March and were responsibly disclosed to the concerned platforms. All three LMS systems have since released patches to address the issues.
It's recommended that users upgrade to the latest versions of these plugins.

UGANDA ELECTORAL COMMISSION TO ELIMINATE NATIONAL IDENTIFICATION CARDS (IDs) FOR 2021 GENERAL ELECTIONS.

By Editor
The elimination of using National IDs (Ndagamuntu) for the 2021 elections should not have come as a surprise. One would be very NAIVE to think that Bobi Wine has not prepared for this in his Business Plan under the RISK section. It is public knowledge that our EC is not independent.  It is also public knowledge that Military Dictator Yoweri Museveni will never lose an election. What stunned us this morning is when we noticed that on social media, people were mocking Bobi with his "get your Ndagamuntu".  We are on record for saying to all Our readers that the National ID is like Apartheid in South Africa. Students of History would know how those IDs were being used to arrest people, deny them jobs, deny them basic services. Consequently, Bobi was not wrong and will never be wrong on the Ndagamuntu. Except the ones attacking him and mocking him forget that in Uganda, now, no National ID (Ndagamuntu), no service.  If you have not been denied registering your child i...

Last week of March, a friend told me to pray for Uganda.  I told him that he was an Idiot and we have prayed for too long and we are still hungry and sick and Jesus is not coming soon to liberate us. He then ignored the STUPID and sent me a picture we all now know.  It got me totally messed up.  This guy was telling me to pray then sends a picture of men bowing down in blood.  He might have meant guns but I blocked him because his utterances of praying for Uganda were misplaced. I unblocked him 3 weeks later and asked him about praying and assassinations.  His reply "eithrr prayers or guns or both". I hate violence with a passion.  So he is now blocked in like FOREVER. Do you feel safe?  Do not feel safe. Uganda regim...

Okello lost his wife 20 years ago and decided to only focus on their Mateo, Yona and Yosefu. 20 years later, Okello had 7 acres of land, a successful poultry business, and sinotrucks for hire. Early this year, Okello got a call telling him that one of his trucks knocked a boda boda. Okello decided to rush to see if he could sort it out before police became involved. Unfortunately, he never made it, as he was entering the main road, another trailer rammed into him and killed him instantly.   After Okello had been laid to rest, his sons sat down and divided the property amongst themselves. However, of late, Yosefu the last born has started complaining that he was cheated, and he wants to be given something else because most of the chicken in the chicken business died of a fever.   Can ...
