CVE-2018-15492

Sentinel License Manager's lservnt.exe (version 8.5.3.35) contains a vulnerability that allows UDP amplification leading to denial of service. The issue arises from failing to validate the source IP address and is fixed in version 8.5.3.2403. Multiple sources (CNVD-2018-16300, NVD CVE-2018-15492)...

Regular Expression Denial of Service in charset

Affected versions of charset are susceptible to a regular expression denial of service. The amplification on this vulnerability is relatively low - it takes around 2 seconds for the engine to execute on a malicious input which is 50,000 characters in length. If node was compiled using the...

Regular Expression Denial of Service in marked

Affected versions of marked are vulnerable to a regular expression denial of service. The amplification in this vulnerability is significant, with 1,000 characters resulting in the event loop being blocked for around 6 seconds. Recommendation Update to version 0.3.9 or later...

memcached: UDP server support allows spoofed traffic amplification DoS

It was discovered that the memcached connections using UDP transport protocol can be abused for efficient traffic amplification distributed denial of service DDoS attacks. A remote attacker could send a malicious UDP request using a spoofed source IP address of a target system to memcached, causi...

Attackers Use UPnP to Sidestep DDoS Defenses

Universal Plug and Play networking protocols have never been a friend of security researchers. On Monday, Imperva gave the InfoSec community another reason to dislike UPnP. In a proof-of-concept Distributed Denial of Service DDoS attack, Imperva researchers have devised a way to exploit the UPnP...

New DDoS Attack Method Demands a Fresh Approach to Amplification Assault Mitigation

Amplification attack vectors are some of the most commonly used tools in the DDoS attacker’s arsenal. In the last quarter of 2017, we saw NTP amplification employed in roughly 33 percent of all DDoS assaults against our customers, while DNS and SSDP amplification vectors played a part in 17 perce...
