WordPress before 5.8 lacks support for the Update URI plugin header. This makes it easier for remote attackers to execute arbitrary code via a supply-chain attack against WordPress installations that use any plugin for which the slug satisfies the naming constraints of the WordPress.org Plugin Directory but is not yet present in that directory. (CVSS:7.5) (Last Update:2021-11-30)
WordPress is affected by an unauthenticated blind SSRF in the pingback feature. Because of a TOCTOU race condition between the validation checks and the HTTP request, attackers can reach internal hosts that are explicitly forbidden. (CVSS:0.0) (Last Update:2022-12-20)
WordPress is a free and open-source content management system written in PHP and paired with a MariaDB database. Due to improper sanitization in WP_Query, there can be cases where SQL injection is possible through plugins or themes that use it in a certain way. This has been patched in WordPress version 5.8.3. Older affected versions are also fixed via security release, that go back till 3.7.37. We strongly recommend that you keep auto-updates enabled. There are no known workarounds for this vulnerability. (CVSS:5.0) (Last Update:2022-04-12)
WordPress is a free and open-source content management system written in PHP and paired with a MariaDB database. Low-privileged authenticated users (like author) in WordPress core are able to execute JavaScript/perform stored XSS attack, which can affect high-privileged users. This has been patched in WordPress version 5.8.3. Older affected versions are also fixed via security release, that go back till 3.7.37. We strongly recommend that you keep auto-updates enabled. There are no known workarounds for this issue. (CVSS:3.5) (Last Update:2022-04-12)
WordPress is a free and open-source content management system written in PHP and paired with a MariaDB database. Due to lack of proper sanitization in one of the classes, there’s potential for unintended SQL queries to be executed. This has been patched in WordPress version 5.8.3. Older affected versions are also fixed via security release, that go back till 4.1.34. We strongly recommend that you keep auto-updates enabled. There are no known workarounds for this issue.

Cross-site scripting vulnerability in WordPress versions prior to 6.0.3 allows a remote unauthenticated attacker to inject an arbitrary script. The developer also provides new patched releases for all versions since 3.7. (CVSS:0.0) (Last Update:2023-02-03)
Cross-site scripting vulnerability in WordPress versions prior to 6.0.3 allows a remote unauthenticated attacker to inject an arbitrary script. The developer also provides new patched releases for all versions since 3.7. (CVSS:0.0) (Last Update:2023-02-03)
Improper authentication vulnerability in WordPress versions prior to 6.0.3 allows a remote unauthenticated attacker to obtain the email address of the user who posted a blog using the WordPress Post by Email Feature. The developer also provides new patched releases for all versions since 3.7. (CVSS:0.0) (Last Update:2023-02-03)
WordPress through 6.1.1 depends on unpredictable client visits to cause wp-cron.php execution and the resulting security updates, and the source code describes “the scenario where a site may not receive enough visits to execute scheduled tasks in a timely manner,” but neither the installation guide nor the security guide mentions this default behavior, or alerts the user about security risks on installations with very few visits.

CVSS v3 9.8
ATTENTION: Exploitable remotely/low attack complexity
Vendor: Rockwell Automation
Equipment: ThinManager ThinServer
Vulnerabilities: Path Traversal, Heap-Based Buffer Overflow
Successful exploitation of these vulnerabilities could allow an attacker to potentially perform remote code execution on the target system/device or crash the software.
The following versions of Rockwell Automation ThinManager ThinServer, a thin client and remote desktop protocol (RDP) server management software, are affected:
ThinManager ThinServer: Versions 6.x – 10.x
ThinManager ThinServer: Versions 11.0.0 – 11.0.5
ThinManager ThinServer: Versions 11.1.0 – 11.1.5
ThinManager ThinServer: Versions 11.2.0 – 11.2.6
ThinManager ThinServer: Versions 12.0.0 – 12.0.4
ThinManager ThinServer: Versions 12.1.0 – 12.1.5
ThinManager ThinServer: Versions 13.0.0 – 13.0.1
3.2.1 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY (‘PATH TRAVERSAL’) CWE-22
In affected versions, a path traversal exists when processing a message. An unauthenticated remote attacker could potentially exploit this vulnerability to upload arbitrary files to any directory on the disk drive where ThinServer.exe is installed. The attacker could overwrite existing executable files with attacker-controlled, malicious contents, potentially causing remote code execution.
CVE-2023-27855 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
3.2.2 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY (‘PATH TRAVERSAL’) CWE-22
In affected versions, a path traversal exists when processing a type 8 message. An unauthenticated remote attacker could exploit this vulnerability to download arbitrary files on the disk drive where ThinServer.exe is installed.
CVE-2023-27856 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
3.2.3 HEAP-BASED BUFFER OVERFLOW CWE-122
In affected versions, a heap-based buffer over-read condition occurs when the message field indicates more data than is present. An unauthenticated remote attacker could exploit this vulnerability to crash ThinServer.exe due to a read access violation.
CVE-2023-27857 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as its connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
