file/show.cgi in Webmin 1.590 and earlier allows remote authenticated users to execute arbitrary commands via an invalid character in a pathname, as demonstrated by a | (pipe) character. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and EPSS exploitation probability 80.0%.
A heap-based buffer overflow flaw was found in the rsync daemon. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Arbitrary file write outside the intended destination in rsync's client-side `--safe-links` handling allows a malicious or compromised rsync server to bypass the symlink safety check via a path-traversal flaw (CWE-22). The client fails to recursively verify whether a symbolic-link target supplied by the server itself contains a nested symlink, so a controlled server can place files anywhere the rsync process can write. A detailed advisory was published by Google's security-research team (GHSA-p5pg-x43v-mvqj) as part of the January 2025 rsync vulnerability cluster, but the issue is not in CISA KEV and no public exploit identified at time of analysis; EPSS is moderate at 2.89% (86th percentile).
Server-to-client path traversal in rsync lets a malicious or compromised rsync server write files outside the client's intended destination directory by abusing the `--inc-recursive` incremental-recursion mode. Because the server can negotiate `--inc-recursive` even when the client does not request it, missing symlink validation combined with per-file-list deduplication allows arbitrary file placement on the connecting client. Publicly available exploit code exists, EPSS is 3.19% (87th percentile), and Red Hat has shipped fixes, but it is not currently listed in CISA KEV.
