Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.14% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs RsyncProject rsync and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Release-specific package status

Alpine, Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

8 package states
Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Summary
A flaw was found in rsync. An rsync daemon configured with "use chroot = no" is exposed to a time-of-check / time-of-use race on parent path components. A local attacker with write access to a module can replace a parent directory component with a symlink between the receiver's check and its open(), redirecting reads (basis-file disclosure) and writes (file overwrite) outside the module. Under elevated daemon privilege this allows privilege escalation. Default "use chroot = yes" is not exposed. Reach: local attacker on the daemon host, write access to a module path, daemon configured with use chroot = no.
Remediation
For OpenShift Container Platform 4.22 see the following documentation, which will be updated shortly for this release, for important instructions on how to upgrade your cluster and fully apply this asynchronous errata update: https://docs.redhat.com/en/documentation/openshift_container_platform/4.22/html/release_notes/ You may download the oc tool and use it to inspect release image metadata for x86_64, s390x, ppc64le, and aarch64 architectures. The image digests may be found at https://quay.io/repository/openshift-release-dev/ocp-release?tab=tags. The sha values for the release are as follows: (For x86_64 architecture) The image digest is sha256:171952b3f8295184cbc98cf89d4aed20e0fbfc06cc95e854d53e8a8a56156490 (For s390x architecture) The image digest is sha256:5d4c79493b883693cfff7222309ece89637bf606f56065d8b5c1ac26acdd2fcf (For ppc64le architecture) The image digest is sha256:7ecf7ab1db0964ab5841c89b48ec6272fe84d1428adde038d59078557752a30e (For aarch64 architecture) The image digest is sha256:4cfd7378ff6b2e188ce37a04cdca2bcf3638ab397f52fb64f92af8cb81859a5f All OpenShift Container Platform 4.22 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift CLI (oc) or web console.

EUVD-2026-31100

No EUVD known-exploited evidence

Rsync versions before 3.4.3 contain a time-of-check to time-of-use (TOCTOU) race condition in daemon file handling that allows attackers to redirect file writes outside intended directories by replacing parent directory components with symbolic links. Attackers with write access to a module path can exploit this race condition to create or overwrite arbitrary files, potentially modifying sensitive system files and achieving privilege escalation when the daemon runs with elevated privileges. This vulnerability can only be triggered if the chroot setting is false.

What, why and how

Rsync versions before 3.4.3 contain a time-of-check to time-of-use (TOCTOU) race condition in daemon file handling that allows attackers to redirect file writes outside intended directories by replacing parent directory components with symbolic links. Attackers with write access to a module path can exploit this race condition to create or overwrite arbitrary files, potentially modifying sensitive system files and achieving privilege escalation when the daemon runs with elevated privileges.

Rsync versions before 3.4.3 contain a time-of-check to time-of-use (TOCTOU) race condition in daemon file handling that allows attackers to redirect file writes outside intended directories by replacing parent directory components with symbolic links. Attackers with write access to a module path can exploit this race condition to create or overwrite arbitrary files, potentially modifying sensitive system files and achieving privilege escalation when the daemon runs with elevated privileges. This vulnerability can only be triggered if the chroot setting is false.

Why

The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
local access → Time-of-check Time-of-use (TOCTOU) Race Condition → gain additional privileges

CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition. The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check.

Rsyncのバージョン3.4.3より前には、デーモンのファイル処理においてチェック時と使用時の時間差（TOCTOU）の競合状態が存在していました。攻撃者は親ディレクトリのコンポーネントをシンボリックリンクに置き換えることで、ファイルの書き込み先を意図したディレクトリ外へリダイレクト可能です。モジュールパスへの書き込みアクセス権を持つ攻撃者は、この競合状態を悪用して任意のファイルを作成または上書きし、機密性の高いシステムファイルを変更することができます。さらに、デーモンが昇格した権限で実行されている場合には、権限昇格を達成する恐れがあります。この脆弱性は、chroot設定がfalseの場合にのみ発生します。
