Attack comes from server to client over network with no auth required; crash is deterministic and confidentiality impact is bounded to four bytes.

Deskflow is a keyboard and mouse sharing app. Prior to continuous build 1.26.0.299, a remote unauthenticated Deskflow server can send kMsgDSetOptions (DSOP) values to ServerProxy::setOptions() in src/lib/client/ServerProxy.cpp so that the value following a modifier option poisons m_modifierTranslationTable, after which ServerProxy::translateKey() or ServerProxy::translateModifierMask() indexes the seven-row s_translationTable or s_masks arrays out of bounds, disclosing four bytes at an attacker-selected relative offset or crashing the connected client; an odd option count also causes an out-of-bounds OptionsList read. This issue is fixed in continuous build 1.26.0.299.
AnalysisAI
Out-of-bounds memory read in Deskflow clients prior to continuous build 1.26.0.299 allows a network-reachable malicious server to crash the connected client or disclose up to four bytes of client process memory at an attacker-controlled relative offset. The flaw lives in ServerProxy::setOptions(), where crafted kMsgDSetOptions (DSOP) option values corrupt m_modifierTranslationTable indexes that translateKey() and translateModifierMask() then use to index static seven-row lookup arrays beyond their valid bounds. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must be running a Deskflow client and must have an active connection to an adversary-controlled or compromised Deskflow server. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 8.2 base score (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H) is well-supported by the description: the attack is fully network-reachable, requires no authentication from the server side, and can deterministically crash the client, justifying the High availability rating. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation is to upgrade all Deskflow client installations to continuous build 1.26.0.299 or later, which introduces std::clamp<KeyModifierMask> bounds enforcement at the setOptions() write path and at both translateKey() and translateModifierMask() read paths. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: conduct an asset inventory to identify all Deskflow client deployments and versions, with priority on identifying any installation prior to build 1.26.0.299. …
