CVE-2023-31147

c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom are unavailable, c-ares uses rand to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand so will generate predictable output. Input from the random number generator i...

Denial Of Service (DoS)

ISC BIND is vulnerable to denial of service DoS. A flaw was found in the way BIND generates outbound DNS query ids. If an attacker is able to acquire a finite set of query IDs, it becomes possible to accurately predict future query IDs. Future query ID prediction may allow an attacker to conduct ...

Bime: Attacker can access graphic representation of every query

Vulnerability details On a dashboard, widgets can be added to show a graphic representation of a query. These queries come from datasources. When creating a widget, a query ID is given. This query ID can be changed in order to obtain the results of the dataset through a scheduled email. This leak...

The vulnerability of the microprogrammed software of the N600 DB Belkin F9K1102 allows a hacker to replace the responses to requests.

The vulnerability of the N600 DB Belkin F9K1102 router’s microprogramming software exists due to the use of an incorrect algorithm for selecting the value of the ID in the DNS query header. Exploiting this vulnerability allows a malicious actor to replace the responses to queries by predicting th...
