CVSS v3.1 |
| 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 a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. |
| 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. |
| 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. |
| Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in support service management in Synology DiskStation Manager (DSM) before 7.0.1-42218-2 allows remote authenticated users to write arbitrary files via unspecified vectors. |
| 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 spoof servers via an HTTP session. |
| Cleartext transmission of sensitive information vulnerability in synoagentregisterd in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows man-in-the-middle attackers to spoof servers via an HTTP session. |
| Unverified password change vulnerability in Change Password in Synology DiskStation Manager (DSM) before 6.2-23739 allows remote authenticated users to reset password without verification. |
| Improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in webapi component in Synology DiskStation Manager (DSM) before 7.0.1-42218-3 allows remote authenticated users to execute arbitrary commands via unspecified vectors. |
| 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. |
| 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. |
| Algorithm downgrade vulnerability in QuickConnect in Synology Router Manager (SRM) before 1.2.4-8081 allows man-in-the-middle attackers to spoof servers and obtain sensitive information via unspecified vectors. |
| Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in PDF Viewer component in Synology DiskStation Manager (DSM) before 6.2.4-25553 allows remote authenticated users to read limited files via unspecified vectors. |
| Buffer copy without checking size of input ('Classic Buffer Overflow') vulnerability in cgi component in Synology Media Server before 1.8.1-2876 allows remote attackers to execute arbitrary code via unspecified vectors. |
| Improper neutralization of special elements used in an SQL command ('SQL Injection') vulnerability in Log Management functionality in Synology DiskStation Manager (DSM) before 7.0.1-42218-2 allows remote attackers to inject SQL commands via unspecified vectors. |
| Command injection vulnerability in EZ-Internet in Synology DiskStation Manager (DSM) before 6.2-23739 allows remote authenticated users to execute arbitrary command via the username 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. |
| 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 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. |
| 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. |
