Cybercriminals Exploiting WooCommerce Payments Plugin Flaw to Hijack Websites

An issue in WooCommerce Payments plugin for WordPress (versions 5.6.1 and lower) allows an unauthenticated attacker to send requests on behalf of an elevated user, like administrator. This allows a remote, unauthenticated attacker to gain admin access on a site that has the affected version of the plugin activated.

CVE-2023-29298 is an improper access control flaw (CWE-284) in Adobe ColdFusion that lets a remote, unauthenticated attacker reach ColdFusion's administrative CFM and CFC endpoints, bypassing the access controls meant to protect them. It is triggered directly over the network with no user interaction and no privileges required (CVSS 3.1: 7.5, high confidentiality impact). An attacker gains access to administrative endpoints as a security feature bypass; in practice, Adobe patched this flaw in the same July 2023 out-of-band update as a critical, actively exploited ColdFusion RCE, and it can be used to reach the server's admin surface. All Adobe ColdFusion deployments running 2018 Update 16 (and earlier), 2021 Update 6 (and earlier), or 2023.0.0.330468 (and earlier) are affected. Exploitation is confirmed in the wild: CISA added it to the KEV on 2023-07-20 and EPSS assigns a 99.8% probability of exploitation within 30 days.

Do: Apply Adobe's July 2023 out-of-band ColdFusion updates immediately - upgrade beyond the affected builds (ColdFusion 2018 later than Update 16, e.g. Update 17; 2021 later than Update 6, e.g. Update 7; and the patched 2023 hotfix newer than build 330468) or follow Adobe's advisory instructions, as CISA requires mitigations or discontinuation of use for KEV entries. Until patched, restrict network access to ColdFusion Administrator/CFIDE endpoints from untrusted networks. Because no authentication or interaction is required, review access logs for unauthenticated requests to admin CFM/CFC endpoints and assume possible compromise on unpatched, internet-facing servers.

CVE-2023-38203 is a critical (CVSS 9.8) deserialization-of-untrusted-data flaw (CWE-502) in Adobe ColdFusion that can lead to arbitrary code execution. It is triggered over the network when an affected ColdFusion server processes crafted untrusted serialized data, and exploitation requires no authentication and no user interaction. A successful attacker gains arbitrary code execution with high impact on confidentiality, integrity, and availability of the host. Organizations running ColdFusion 2018 (Update 17 or earlier), ColdFusion 2021 (Update 7 or earlier), or ColdFusion 2023 (Update 1 or earlier) are affected. The flaw is being actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2024-01-08 with known ransomware use, EPSS assigns a 96.7% probability of exploitation within 30 days (100th percentile), and Adobe has shipped out-of-band patches in response.

Do: Upgrade all ColdFusion 2018, 2021, and 2023 installations beyond the affected levels (at least past 2018u17, 2021u7, and 2023u1, using the latest update Adobe provides in its advisory). If patching must be delayed, apply the mitigations per Adobe's instructions, restrict or remove internet exposure of ColdFusion servers, and prioritize internet-facing hosts. Because exploitation is confirmed with known ransomware use, review ColdFusion logs and affected hosts for signs of exploitation, webshells, or follow-on malware, and discontinue use of the product if mitigations are unavailable per CISA's required action.
