CVE-2020-27648 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2025-01-14 6.8 MEDIUM 8.3 HIGH
Improper certificate validation vulnerability in OpenVPN client in Synology DiskStation Manager (DSM) before 6.2.3-25426-2 allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVE-2019-9517 12 Apache, Apple, Canonical and 9 more 25 Http Server, Traffic Server, Mac Os X and 22 more 2025-01-14 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.
CVE-2020-27650 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2025-01-14 4.3 MEDIUM 5.8 MEDIUM
Synology DiskStation Manager (DSM) before 6.2.3-25426-2 does not set the Secure flag for the session cookie in an HTTPS session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an HTTP session.
CVE-2021-26565 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 4.3 MEDIUM 8.3 HIGH
Cleartext transmission of sensitive information vulnerability in synorelayd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to obtain sensitive information via an HTTP session.
CVE-2019-3870 3 Fedoraproject, Samba, Synology 9 Fedora, Samba, Directory Server and 6 more 2025-01-14 3.6 LOW 6.1 MEDIUM
A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8. Within this directory, files are created with mode 0666, which is world-writable, including a sample krb5.conf, and the list of DNS names and servicePrincipalName values to update.
CVE-2017-5753 13 Arm, Canonical, Debian and 10 more 387 Cortex-a12, Cortex-a12 Firmware, Cortex-a15 and 384 more 2025-01-14 4.7 MEDIUM 5.6 MEDIUM
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
CVE-2021-26566 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 6.8 MEDIUM 8.3 HIGH
Insertion of sensitive information into sent data vulnerability in synorelayd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to execute arbitrary commands via inbound QuickConnect traffic.
CVE-2021-26561 1 Synology 7 Diskstation Manager, Diskstation Manager Unified Controller, Skynas and 4 more 2025-01-14 6.8 MEDIUM 9.0 CRITICAL
Stack-based buffer overflow vulnerability in synoagentregisterd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to execute arbitrary code via syno_finder_site HTTP header.
CVE-2018-8897 8 Apple, Canonical, Citrix and 5 more 11 Mac Os X, Ubuntu Linux, Xenserver and 8 more 2024-11-21 7.2 HIGH 7.8 HIGH
A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs.
