CISA released two Industrial Control Systems (ICS) advisories on June 8, 2023. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.
CISA encourages users and administrators to review the newly released ICS advisories for technical details and mitigations.
CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.
These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Note: To view other newly added vulnerabilities in the catalog, click on the arrow in the “Date Added to Catalog” column—which will sort by descending dates.
Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.
Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
Mozilla has released security updates to address vulnerabilities for Firefox 114 and Firefox ESR 102.12. An attacker could exploit these vulnerabilities to take control of an affected system.
CISA encourages users and administrators to review Mozilla’s security advisories for Firefox 114 and Firefox ESR 102.12 for more information and apply the necessary updates.
CISA and FBI released a joint Cybersecurity Advisory (CSA) [CL0P Ransomware Gang Exploits MOVEit Vulnerability] in response to a recent vulnerability exploitation attributed to CL0P Ransomware Gang. This [joint guide] provides indicators of compromise (IOCs) and tactics, techniques, and procedures (TTPs) identified through FBI investigations as recently as May this year. Additionally, it provides immediate actions to help reduce the impact of CL0P ransomware.
The CL0P Ransomware Gang, also known as TA505, reportedly began exploiting a previously unknown SQL injection vulnerability in Progress Software’s managed file transfer (MFT) solution known as MOVEit Transfer. Internet- facing MOVEit Transfer web applications were infected with a web shell named LEMURLOOT, which was then used to steal data from underlying MOVEit Transfer databases.
CISA and FBI encourage information technology (IT) network defenders to review the MOVEit Transfer Advisory and implement the recommended mitigations to reduce the risk of compromise. This joint CSA is part of an ongoing #StopRansomware effort to publish advisories for network defenders that detail various ransomware variants and ransomware threat actors. These #StopRansomware advisories include recently and historically observed TTPs and IOCs to help organizations protect against ransomware. Visit stopransomware.gov to see all #StopRansomware advisories and to learn more about other ransomware threats and no-cost resources.
Today, CISA, Federal Bureau of Investigation (FBI), the National Security Agency (NSA), Multi-State Information Sharing and Analysis Center (MS-ISAC), and the Israel National Cyber Directorate (INCD) released the Guide to Securing Remote Access Software. This new joint guide is the result of a collaborative effort to provide an overview of legitimate uses of remote access software, as well as common exploitations and associated tactics, techniques, and procedures (TTPs), and how to detect and defend against malicious actors abusing this software.
Remote access software provides organizations with a broad array of capabilities to maintain and improve information technology (IT), operational technology (OT), and industrial control system (ICS) services; however, malicious actors often exploit this software for easy and broad access to victim systems.
CISA encourages organizations to review this joint guide for recommendations and best practices to implement in alignment with their specific cybersecurity requirements to better detect and defend against exploitation. Additionally, please refer to the additional information below on guidance for MSPs and small- and mid-sized businesses and on malicious use of remote monitoring and management software in using remote software and implementing mitigations.
CISA released two Industrial Control Systems (ICS) advisories on June 6, 2023. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.

Today, CISA, the Federal Bureau of Investigation (FBI), the National Security Agency (NSA), the Multi-State Information Sharing and Analysis Center (MS-ISAC), and the Israel National Cyber Directorate (INCD) published the Guide to Securing Remote Access Software to provide organizations with an overview of common remote access exploitations and associated tactics, techniques, and procedures (TTPs).
The Guide to Securing Remote Access Software provides organizations with a remote access software overview, including the malicious use of remote access software, detection methods, and recommendations for all organizations. Remote access software provides a proactive and flexible approach for organizations to internally oversee networks, computers, and other devices; however, cyber threat actors increasingly co-opt these tools for access to victim systems.
CISA encourages organizations to use the provided additional information on remote management and on malicious use of remote monitoring and management software in implementing remote software and remote software mitigations.
CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.
These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Note: To view other newly added vulnerabilities in the catalog, click on the arrow in the “Date Added to Catalog” column—which will sort by descending dates.
Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.
Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
