Vulnerabilities

SKYSEA Client View and SKYMEC IT Manager provided by Sky Co.,LTD. configure the installation folder with improper file access permission settings. A non-administrative user may manipulate and/or place arbitrary files within the installation folder of the product. As a result, arbitrary code may be executed with the administrative privilege.

Incorrect privilege assignment vulnerability exists in SKYSEA Client View Ver.6.010.06 to Ver.19.210.04e. If a user who can log in to the PC where the product's Windows client is installed places a specially crafted DLL file in a specific folder, arbitrary code may be executed with SYSTEM privilege.

Improper access control vulnerability exists in the specific folder of SKYSEA Client View versions from Ver.16.100 prior to Ver.19.2. If this vulnerability is exploited, an arbitrary file may be placed in the specific folder by a user who can log in to the PC where the product's Windows client is installed. In case the file is a specially crafted DLL file, arbitrary code may be executed with SYSTEM privilege.

"FFRI yarai", "FFRI yarai Home and Business Edition" and their OEM products handle exceptional conditions improperly, which may lead to denial-of-service (DoS) condition. Affected products and versions are as follows: FFRI yarai versions 3.4.0 to 3.4.6 and 3.5.0, FFRI yarai Home and Business Edition version 1.4.0, InfoTrace Mark II Malware Protection (Mark II Zerona) versions 3.0.1 to 3.2.2, Zerona / Zerona PLUS versions 3.2.32 to 3.2.36, ActSecure χ versions 3.4.0 to 3.4.6 and 3.5.0, Dual Safe Powered by FFRI yarai version 1.4.1, EDR Plus Pack (Bundled FFRI yarai versions 3.4.0 to 3.4.6 and 3.5.0), and EDR Plus Pack Cloud (Bundled FFRI yarai versions 3.4.0 to 3.4.6 and 3.5.0).

Untrusted search path vulnerability in the installer of SKYSEA Client View Ver.1.020.05b to Ver.16.001.01g allows an attacker to gain privileges via a Trojan horse DLL in an unspecified directory.

Privilege escalation vulnerability in SKYSEA Client View Ver.12.200.12n to 15.210.05f allows an attacker to obtain unauthorized privileges and modify/obtain sensitive information or perform unintended operations via unspecified vectors.

SKYSEA Client View Ver.11.221.03 and earlier contains an improper authentication flaw (CWE-287) in the processing of authentication on the TCP connection used with the management console program. An attacker with network reachability to that TCP service can send crafted authentication data that triggers remote code execution with no credentials, no user interaction, and no special conditions (CVSS 3.1: 9.8). Successful exploitation gives the attacker full code execution on the console side, with high impact to confidentiality, integrity, and availability, and potential access to the managed-client inventory the console controls. Organizations running SKYSEA Client View Ver.11.221.03 or earlier are affected; the product is a client/IT-asset management suite deployed largely by Japanese organizations. CISA added the vulnerability to its Known Exploited Vulnerabilities catalog on October 14, 2025, indicating confirmed in-the-wild exploitation, and EPSS currently estimates a 19.4% probability of exploitation within 30 days.

Do: Upgrade SKYSEA Client View to a fixed release later than Ver.11.221.03 as directed in Sky Group's security advisory (https://www.skygroup.jp/security-info/170308.html), and inventory any console running Ver.11.221.03 or older. Until patched, restrict access to the management console TCP port from untrusted network segments and review console servers for signs of compromise. CISA KEV requires applying vendor mitigations or discontinuing use within the BOD 22-01 timeline.
