Exploitation evidence

Disclosed: evidence found.
CVE published 14 Nov 2023
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade asyncssh to 2.14.1.

AI-suggested

Upgrade AsyncSSH to version 2.14.1 or later, where this vulnerability is fixed. No other mitigations are specified.

Description

AsyncSSH versions prior to 2.14.1 contain a vulnerability that allows attackers to manipulate the remote end of an SSH client session through packet injection or removal and shell emulation. This issue, known as the "Rogue Session Attack," enables unauthorized control over the SSH session. The vulnerability is fixed in version 2.14.1.

Impact

Attackers exploiting this vulnerability can gain control over the remote end of an SSH client session, potentially allowing unauthorized command execution or session manipulation. This compromises the security and trustworthiness of SSH client connections using affected AsyncSSH versions.

Summary

CVE-2023-46446 describes a vulnerability in AsyncSSH before version 2.14.1 where attackers can control the remote end of an SSH client session by injecting or removing packets and emulating the shell. This flaw allows a rogue session attack, compromising the integrity of the SSH client session. The issue is resolved in AsyncSSH version 2.14.1.
