The MOVEIt data breach continues to impact a number of both private and government groups across the US and Europe by exposing confidential data. With breaches like this becoming increasingly common, it can be easy to blame advanced persistent threat (APT) groups and other malicious actors; however, there is a valuable lesson to learn from the MOVEit breach: it is essential to be proactive about these threats, Not doing so may lead to a breach.

In quick succession at the end of May into mid-June, software developer Progress released three advisories that any customers using its popular managed file transfer (MFT) solution MOVEit should immediately update to the latest release. In this time, they were made aware of three critical vulnerabilities, CVE-2023-34362 on May 31, CVE-2023-35036 on June 9, and CVE-2023-35708 on June 15.

In the December of last year, we reported CVE-2022-1471 to you. This unsafe deserialization problem could easily lead to arbitrary code execution under the right circumstances. In the deep-dive blog post “Unsafe deserialization vulnerability in SnakeYaml (CVE-2022-1471)”, I explained the problems in this library and how it could be executed. The gist of the problem was that by default SnakeYaml parsed the incoming yaml to the generic object type.

On June 15, 2023, Progress Software announced a critical vulnerability in the MOVEit file transfer software (CVE-2023-35708). This was the third vulnerability impacting the file transfer software (May 2023: CVE-2023-34362; June 9: CVE-2023-35036). The vulnerabilities have been fixed, and all MOVEit Transfer customers are strongly urged to immediately apply all applicable patches.

After a wave of zero-day attacks targeting widely used security and networking appliances, the Cybersecurity & Infrastructure Security Agency (CISA) is taking new measures to protect Internet-exposed networking equipment.

In our final OT:ICEFALL report, Forescout Vedere Labs presents three new vulnerabilities and concludes the project after one year of research following the original disclosure. The OT:ICEFALL research, including 61 vulnerabilities affecting 13 vendors, has yielded three key insights into the current state of OT product security.

Kubernetes “crossed the adoption chasm” in 2021 after 5.6 million developers used it to orchestrate their containers, according to the Cloud Native Computing Federation (CNCF). The annual CNCF survey recorded that an impressive 96% of organizations were either contemplating or outright using Kubernetes. However, Kubernetes becomes more appealing to hackers and malefactors as it becomes more popular.

Progress has recently raised concerns about multiple vulnerabilities in their MOVEit Transfer secure managed file transfer solution. These vulnerabilities have been publicly disclosed within the past several weeks, and the most recent one was reported on June 15, 2023. Notably, the latest vulnerability is claimed to be a zero-day SQL injection vulnerability. If exploited by an attacker, these vulnerabilities can lead to unauthorized access to the MOVEit Transfer database.

New disclosures regarding the widespread exploitation of CVE-2023-34362, a new vulnerability affecting the MOVEit file transfer software, and the Cl0p ransomware group’s claim of responsibility for its widespread exploitation and the resulting data theft, have continued in the weeks since the vulnerability’s original publication.

In the past two weeks, three new vulnerabilities in the the MOVEit file transfer software have been discovered, including one over the weekend. The MOVEit file transfer software is used by around 1700 organizations worldwide. As in most cases when supply chain modules are being compromised, the impact is lethal as big companies such as the BBC and Zellis have been targeted.
