CVE-2025-2244 |
Description: A vulnerability in the sendMailFromRemoteSource method in Emails.php as used in Bitdefender GravityZone Console unsafely uses php unserialize() on user-supplied input without validation. By crafting a malicious serialized payload, an attacker can trigger PHP object injection, perform a file write, and gain arbitrary command execution on the host system.

CVE-2025-2780 |
Description: The Woffice Core plugin for WordPress, used by the Woffice Theme, is vulnerable to arbitrary file uploads due to missing file type validation in the 'saveFeaturedImage' function in all versions up to, and including, 5.4.21. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

CVE-2024-13645 |
Description: The tagDiv Composer plugin for WordPress is vulnerable to PHP Object Instantiation in all versions up to, and including, 5.3 via module parameter. This makes it possible for unauthenticated attackers to Instantiate a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

🚨 Marked as known exploited on April 10th, 2025 (2 months ago).
Description: Ivanti has disclosed details of a now-patched critical security vulnerability impacting its Connect Secure that has come under active exploitation in the wild.
The vulnerability, tracked as CVE-2025-22457 (CVSS score: 9.0), concerns a case of a stack-based buffer overflow that could be exploited to execute arbitrary code on affected systems.

CVE-2025-31161 |
🚨 Marked as known exploited on April 3rd, 2025 (2 months ago).
Description: CrushFTP 10 before 10.8.4 and 11 before 11.3.1 allows authentication bypass and takeover of the crushadmin account (unless a DMZ proxy instance is used), as exploited in the wild in March and April 2025, aka "Unauthenticated HTTP(S) port access." A race condition exists in the AWS4-HMAC (compatible with S3) authorization method of the HTTP component of the FTP server. The server first verifies the existence of the user by performing a call to login_user_pass() with no password requirement. This will authenticate the session through the HMAC verification process and up until the server checks for user verification once more. The vulnerability can be further stabilized, eliminating the need for successfully triggering a race condition, by sending a mangled AWS4-HMAC header. By providing only the username and a following slash (/), the server will successfully find a username, which triggers the successful anypass authentication process, but the server will fail to find the expected SignedHeaders entry, resulting in an index-out-of-bounds error that stops the code from reaching the session cleanup. Together, these issues make it trivial to authenticate as any known or guessable user (e.g., crushadmin), and can lead to a full compromise of the system by obtaining an administrative account.

CVE-2025-30406 |
🚨 Marked as known exploited on April 8th, 2025 (2 months ago).
Description: Gladinet CentreStack through 16.1.10296.56315 (fixed in 16.4.10315.56368) has a deserialization vulnerability due to the CentreStack portal's hardcoded machineKey use, which enables threat actors (who know the machineKey) to serialize a payload for server-side deserialization to achieve remote code execution. NOTE: the CentreStack admin can manually delete the machineKey defined in portal\web.config.
According to Huntress:
"It is very important to note that this weakness also affects Gladinet Triofox, up to version 16.4.10317.56372. By default, previous versions of the Triofox software have the same hardcoded cryptographic keys in their configuration file, and can be easily abused for remote code execution." See references.

CVE-2025-22457 |
🚨 Marked as known exploited on April 3rd, 2025 (2 months ago).
Description: On Thursday, April 3, 2025, Ivanti disclosed a critical security vulnerability, CVE-2025-22457, impacting Ivanti Connect Secure (“ICS”) VPN appliances version 22.7R2.5 and earlier. CVE-2025-22457 is a buffer overflow vulnerability, and successful exploitation would result in remote code execution. Mandiant and Ivanti have identified evidence of active exploitation in the wild against ICS 9.X (end of life) and 22.7R2.5 and earlier versions. Ivanti and Mandiant encourage all customers to upgrade as soon as possible.
The earliest evidence of observed CVE-2025-22457 exploitation occurred in mid-March 2025. Following successful exploitation, we observed the deployment of two newly identified malware families, the TRAILBLAZE in-memory only dropper and the BRUSHFIRE passive backdoor. Additionally, deployment of the previously reported SPAWN ecosystem of malware attributed to UNC5221 was also observed. UNC5221 is a suspected China-nexus espionage actor that we previously observed conducting zero-day exploitation of edge devices dating back to 2023.
A patch for CVE-2025-22457 was released in ICS 22.7R2.6 on February 11, 2025. The vulnerability is a buffer overflow with a limited character space, and therefore it was initially believed to be a low-risk denial-of-service vulnerability. We assess it is likely the threat actor studied the patch for the vulnerability in ICS 22.7R2.6 and uncovered through a complicated process, it was possible to exploit 22.7R2.5 and earlier to achiev...
