9Front
Monthly
Remote denial-of-service in 9front (a fork of Plan 9 from Bell Labs) allows unauthenticated network attackers to trigger a kernel panic by sending malformed TCP, IL, RUDP, or GRE packets whose total length is shorter than the protocol header size. The flaw affects 9front Plan 9 4e prior to commit 70c97c334171c715df82774d1a47638abaca2db4 and carries a CVSS 4.0 score of 9.2 driven by high availability impact and automatable exploitation; no public exploit identified at time of analysis.
File disclosure via malicious HTML file upload default values in Mothra, the web browser bundled with the 9front Plan 9 fork, allows a remote unauthenticated attacker to exfiltrate arbitrary local files from a victim's filesystem. By crafting a webpage containing a hidden file input element with a pre-set malicious default path, the attacker can cause Mothra to silently submit a targeted local file to an attacker-controlled server upon user interaction. The CVSS 4.0 E:P supplemental metric indicates publicly available proof-of-concept exploit code exists; no CISA KEV listing is present, suggesting exploitation is not yet confirmed at scale.
A bug in the 9p authentication implementation within lib9p allows an attacker with an existing valid user within the configured auth server to impersonate any other valid filesystem user. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity.
