| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2007-4411 | ircu 2.10.12.05 and earlier allows remote attackers to discover the hidden IP address of arbitrary +x users via a series of /silence commands with (1) CIDR mask arguments or (2) certain other arguments that represent groups of IP addresses, then monitoring CTCP ping replies. | [email protected] | 4.3 | 0.39% | 2007-08-18 | 2026-04-23 |
| CVE-2007-4410 | ircu 2.10.12.05 and earlier does not properly synchronize a kick action in certain cross scenarios, which allows remote authenticated operators to prevent later kick or de-op actions from non-local ops. | [email protected] | 6.0 | 0.88% | 2007-08-18 | 2026-04-23 |
| CVE-2007-4409 | Race condition in ircu 2.10.12.01 through 2.10.12.05 allows remote attackers to set a new Apass during a netburst by arranging for ops privilege to be granted before the mode arrives. | [email protected] | 5.1 | 0.89% | 2007-08-18 | 2026-04-23 |
| CVE-2007-4408 | ircu 2.10.12.05 and earlier ignores timestamps in bounces, which allows remote attackers to take over a channel during a netjoin by causing a bounce while a server with an older version of the channel is linking. | [email protected] | 5.0 | 0.46% | 2007-08-18 | 2026-04-23 |
| CVE-2007-4407 | ircu 2.10.12.03 and 2.10.12.04 does not associate a timestamp with ops privilege on an unused channel (zannel), which allows remote attackers to (1) set or remove certain channel modes via a "netriding" attack or (2) take over a channel by joining an unlinked server with the A/Upass and then setting a new Apass. | [email protected] | 6.4 | 0.89% | 2007-08-18 | 2026-04-23 |
| CVE-2007-4406 | ircu 2.10.12.01 through 2.10.12.04 does not remove ops privilege after a join from a server with an older timestamp (TS), which allows remote attackers to gain control of a channel during a split. | [email protected] | 7.5 | 0.73% | 2007-08-18 | 2026-04-23 |
| CVE-2007-4405 | ircu 2.10.12.02 through 2.10.12.04 allows remote attackers to cause a denial of service (memory and bandwidth consumption) by creating a large number of unused channels (zannels). | [email protected] | 7.8 | 0.88% | 2007-08-18 | 2026-04-23 |
| CVE-2007-4404 | ircu 2.10.12.01 allows remote attackers to (1) cause a denial of service (flood wallops) by joining two channels with certain long names that differ in the final character, which triggers a protocol violation and (2) cause a denial of service (daemon crash) via a "J 0:#channel" message on a channel without an apass; and (3) allows remote authenticated operators to cause a denial of service (daemon crash) via a remote "names -D" command. | [email protected] | 7.8 | 3.01% | 2007-08-18 | 2026-04-23 |
