Technical description

As part of Cisco's ongoing commitment to proactive security and product quality, engineering teams for Cisco Emergency Responder, Cisco Prime Collaboration Deployment, Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unity Connection have conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities. The vulnerabilities tracked by CVE-2026-76479 are related to issues concerning improper limitation of a pathname to a restricted directory that are grouped under the Common Weakness Enumeration (CWE) Base CWE-22.

CVE-2026-927098.1 HIG

—

———Rsyslog is a rocket-fast system for log processing. From versions 1.15.0 to 8.2610.0, rsyslog's omfile dynaFile facility intentionally allows templates to generate flexible output paths. This supports valid deployments that route logs into different directories or use dynamically generated file names. A deployment becomes unsafe when a dynaFile template uses a value influenced by untrusted input as a path component without explicit secure-path handling. In that configuration, the rendered path can escape the operator's intended log directory. This is not limited to the RFC5424 HOSTNAME field. Any untrusted value that reaches a dynaFile path component can create the condition. At time of publication, there are no publicly available patches.8h CVE-2026-1152075.5 MED

—

———A flaw was found in GNU patch. An attacker can achieve arbitrary file creation outside the intended working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to missing validation during automatic patch reversal, absolute file paths in patch headers are accepted rather than rejected. Consequently, the utility can create files in arbitrary locations with the permissions of the executing user.6h CVE-2024-583967.5 HIG

—

———YouDataSum CPAS Audit Management System V4 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by manipulating the fileId parameter. Attackers can send GET requests to /cpasm4/plugInManController/downPlugs with ../ sequences in fileId to retrieve system files like /etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-01-13.11h CVE-2022-510256.5 MED

—

———Penta Security WAPPLES 4.0.54.1, 5.0, and 6.0 contains a path traversal vulnerability that allows authenticated attackers to download arbitrary files via the name parameter of /webapi/file/transfer. Attackers can send GET requests with type=db_backup and ../ sequences in name to read files like /etc/passwd, and a hardcoded systemi account makes authentication effectively trivial. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.11h CVE-2022-510247.5 HIG

—

———Kavita 0.5.2 before 0.5.4.1 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by supplying '../' sequences in the filename parameter. Attackers can send GET requests to /api/image/cover-upload with filename values like ../appsettings.json to retrieve configuration files outside the temp directory. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.11h CVE-2022-510229.1 CRI

—

———YiShaAdmin 2.2 through 3.1, fixed in commit 025b062, contains an unauthenticated path traversal vulnerability in the /admin/File/DownloadFile endpoint that allows attackers to read and delete arbitrary files via the filePath parameter. Attackers can send crafted GET requests with directory traversal sequences in filePath and set the delete parameter to read or remove system files like etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-20.11h
