CVSS v3.1 |
| 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. |
| Cleartext transmission of sensitive information vulnerability in DDNS in Synology DiskStation Manager (DSM) before 6.2.3-25426-2 allows man-in-the-middle attackers to eavesdrop authentication information of DNSExit via unspecified vectors. |
| 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. |
| Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU. |
| 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. |
| ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an incomplete fix for CVE-2016-1549. |
| Cross-site scripting (XSS) vulnerability in SYNO.Core.PersonalNotification.Event in Synology DiskStation Manager (DSM) before 6.1.4-15217-3 allows remote authenticated users to inject arbitrary web script or HTML via the package parameter. |
| Use of insufficiently random values vulnerability in SYNO.Encryption.GenRandomKey in Synology DiskStation Manager (DSM) before 6.2-23739 allows man-in-the-middle attackers to compromise non-HTTPS sessions via unspecified vectors. |
| Information exposure vulnerability in SYNO.Core.ACL in Synology DiskStation Manager (DSM) before 6.2-23739-2 allows remote authenticated users to determine the existence and obtain the metadata of arbitrary files via the file_path parameter. |
| Uncontrolled search path element vulnerability in Backup Management functionality in Synology DiskStation Manager (DSM) before 6.2.4-25556-8, 7.0.1-42218-7 and 7.1-42661 allows remote authenticated users with administrator privileges to read or write arbitrary files via unspecified vectors. |
| Use of insufficiently random values vulnerability in User Management Functionality in Synology DiskStation Manager (DSM) before 7.2-64561 allows remote attackers to obtain user credential via unspecified vectors. |
| Command injection vulnerability in ftpd in Synology Diskstation Manager (DSM) before 6.2-23739-1 allows remote authenticated users to execute arbitrary OS commands via the (1) MKD or (2) RMD command. |
| Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory. |
| Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. |
| Incorrect default permissions vulnerability in synouser.conf in Synology Diskstation Manager (DSM) before 6.2-23739-1 allows remote authenticated users to obtain sensitive information via the world readable configuration. |
| Information exposure vulnerability in /usr/syno/etc/mount.conf in Synology DiskStation Manager (DSM) before 6.2.1-23824 allows remote authenticated users to obtain sensitive information via the world readable configuration. |
| Cross-site scripting (XSS) vulnerability in Control Panel SSO Settings in Synology DiskStation Manager (DSM) before 6.2.1-23824 allows remote authenticated users to inject arbitrary web script or HTML via the URL parameter. |
| ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704. |
| Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. |
| Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. |
