No EUVD known-exploited evidence

MobSF is a mobile application security testing tool used. Prior to 4.5.1, find_icon_path_zip in mobsf/StaticAnalyzer/views/android/icon_analysis.py uses the Android manifest android:icon value to construct paths under the scan resource directory without rejecting traversal or verifying containment, allowing an authenticated user to upload a crafted ZIP or APK that reads a server file with an ALLOWED_EXTENSIONS suffix, copies it to DWD_DIR as the predictable name -icon., and retrieves it through the /download/ endpoint. The same behavior provides a file-existence oracle through the icon_path report field. This issue is fixed in version 4.5.1.

What, why and how

MobSF is a mobile application security testing tool used. Prior to 4.5.1, find_icon_path_zip in mobsf/StaticAnalyzer/views/android/icon_analysis.py uses the Android manifest android:icon value to construct paths under the scan resource directory without rejecting traversal or verifying containment, allowing an authenticated user to upload a crafted ZIP or APK that reads a server file with an ALLOWED_EXTENSIONS suffix, copies it to DWD_DIR as the predictable name -icon., and retrieves it through the /download/ endpoint. The same behavior provides a file-existence oracle through the icon_path report field. This issue is fixed in version 4.5.1.

The same behavior provides a file-existence oracle through the icon_path report field. This issue is fixed in version 4.5.1.

Why

Attacker-controlled path data is not constrained to the intended directory before the application accesses a file.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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.
Reference recorded

CISA Vulnrichment records proof-of-concept exploitation in its SSVC data. BlackTree has not independently executed or validated exploit material.

Likely attack path
a network path → Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') → cause the confidentiality, integrity or availability impact described by the vendor

Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-22 ↗

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'). The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:N

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRHighPrivileges required: The attacker needs elevated or administrative privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.ILowIntegrity impact: A successful attack can cause a limited loss.ANoneAvailability impact: No direct loss is represented by this metric.
