The MOVEit Transfer story continues to plague IT departments and security professionals as Progress Software has issued another advisory, urging organizations to apply yet another patch to address a privilege escalation flaw in its Transfer product.
The company’s update comes amid reports of widespread exploitation, including several at several U.S. agencies that were breached as part of the attack. Cybersecurity researchers say ransomware groups have seized upon the vulnerability and are using it to exfiltrate data to compel victim organizations to pay the ransom.
In the advisory, dated June 16, Progress says it has discovered vulnerability in MOVEit Transfer that could lead to escalated privileges and potential unauthorized access to the environment.
“If you are a MOVEit Transfer customer, it is extremely important that you take immediate action as noted below in order to help protect your MOVEit Transfer environment,” the company says in the new advisory. “In Progress MOVEit Transfer versions released before 2021.0.8 (13.0.8), 2021.1.6 (13.1.6), 2022.0.6 (14.0.6), 2022.1.7 (14.1.7), 2023.0.3 (15.0.3), a SQL injection vulnerability has been identified in the MOVEit Transfer web application that could allow an un-authenticated attacker to gain unauthorized access to the MOVEit Transfer database. An attacker could submit a crafted payload to a MOVEit Transfer application endpoint which could result in modification and disclosure of MOVEit database content.”
The incident, which was first identified in late May, now stretches well into June as organizations rush to patch their systems and protect their environment.
According to Progress Software, “All MOVEit Transfer customers must take action and apply the patch to address the June 15th CVE-2023-35708 vulnerability discovered in MOVEit Transfer. “
However, organizations have two paths to take, depending on if they applied the remediation and patching steps from the first MOVEit Transfer Critical Vulnerability (May 2023) advisory prior to June 15.
For those who have not yet applied the May 2023 patch, they should do so and follow the remediation steps immediately, the company says. This includes the newest patch for two separate vulnerabilities, including the original from May 31 (CVE-2023-34362) and another identified on June 9 (CVE-2023-35036).
Once that is taken care of, organizations should apply the June 15 patch (CVE-2023-35708).
If organizations have applied the May 31 and June 9 patch, they should now apply the June 15 patch, which will bring them fully up to date.
