18 Unrestricted Access JAN 2021
WordPress Security Report January 2022
Be informed about the latest Unrestricted Access JAN 2021 Circumvention, identified and reported publicly in January 2022. These breaches create even more problems and vulnerability exploitation with a severe negative impact on any WordPress Security. Consider our FREE security AUDIT.
An estimated 493.000 active WordPress installations are susceptible to these attack types, considering only the publicly available numbers. The estimated number can double with premium versions as they are private purchases.
Furthermore, the initial estimation can multiply if we consider the already patched versions BUT NOT UPDATED by owners, as the vulnerability remains active within their domain. As these owners start changing their hosting provider (due to constant unexplained issues), they actively migrate these vulnerabilities behind protected areas, possibly exposing other clean WP to different attack types.
It is a 260% increase compared to December 2020. Read more about our previous report here: 5 Unrestricted Access Issues – WordPress Security DEC. The following cases made headlines PUBLICLY just last month in the SQL Injections JAN 2021 category:

Do you suspect any Unrestricted Access JAN 2021 within your WP?
BRIEF: Open and Unrestricted Access JAN 2021 to anything within a website is one thing everybody considers to be a total disaster. Many employees have come to rely on the Internet both for work and day-to-day life. As such, they demand unrestricted access at work, and many company bosses have obliged. Without the knowledge to them, however, there may be a risk associated with this.
What is Unauthenticated Insecure Deserialisation?
Insecure Deserialization is a vulnerability which occurs when untrusted data is used to abuse the logic of an application, inflict a denial of service (DoS) attack, or even execute arbitrary code upon it being deserialized. If the function that is responsible for converting serial data into a structured object assumes that the data is trusted, an attacker may format the serial data in such a way that the result of deserialization is malicious. Unfortunately, many standard deserialization functions in programming languages assume that the data is safe.
What is Unauthenticated Backup Download?
The plugin does not restrict access to a BACKUP file containing sensitive information, such as the internal path of backups, which may then allow unauthenticated users to download them.
What is Unrestricted File Upload?
By exploiting this vulnerability, attackers could simply upload files of any type, bypassing all restrictions placed regarding the allowed upload-able file types on a website. By doing this, it allows an attacker to inject malicious content such as web shells into the sites, and providing a method for initial access into the system.
What is Login Rate Limiting Bypass?
When the plugin is configured with a custom header in its Trusted IP Origins setting (e.g X-Forwarded-For), attackers could bypass the protection offered by tampering the header sent in requests. When the plugin is configured to accept an arbitrary header as client source IP address, a malicious user is not limited to perform a brute force attack, because the client IP header accepts any arbitrary string. When randomizing the header input, the login count does never reach the maximum allowed retries.
What is Improper Authorisation Check?
An attacker could leverage these issues to dump the database including administrative user credentials, to steal cookie-based authentication credentials, or launch other attacks. An anonymous user may create a new dive entry with a crafted HTTP POST.
