CVE-2026-48448: Adobe Campaign Classic SQL Injection Flaw

CVE-2026-48448 Overview

CVE-2026-48448 is a SQL injection vulnerability in Adobe Campaign Classic (ACC) that allows attackers to disclose sensitive memory and gain file system read access. The flaw stems from improper neutralization of special elements used in SQL commands [CWE-89]. The vulnerability is exploitable over the network without authentication or user interaction. The scope is changed, meaning successful exploitation impacts resources beyond the vulnerable component. Adobe published details in security advisory APSB26-114.

Critical Impact
Unauthenticated network attackers can inject SQL commands to read sensitive memory contents and access files on the underlying system, potentially exposing credentials, campaign data, and customer records managed by Adobe Campaign Classic.

Technical Details for CVE-2026-48448

Vulnerability Analysis

Adobe Campaign Classic fails to properly neutralize special characters passed into SQL statements. Attackers submit crafted input that alters the intended query structure. The resulting query executes with the privileges of the ACC database context. Because the scope is changed, the impact extends beyond the vulnerable component to protected resources. In this case, the SQL injection is leveraged to disclose sensitive memory contents and read files from the underlying file system. Exploitation requires no authentication and no user interaction, which increases the exposure of internet-facing deployments.

Root Cause

The root cause is improper input validation in query construction paths within Adobe Campaign Classic. User-supplied values are concatenated into SQL statements without adequate sanitization or parameterization, allowing injected clauses to modify query semantics and trigger information disclosure primitives that reach memory and file system state.

Attack Vector

An unauthenticated remote attacker sends crafted HTTP requests to a network-reachable ACC endpoint. Injected SQL payloads manipulate backend queries to return data from memory buffers and read files accessible to the database or application context. No user interaction is required. See the Adobe Security Advisory APSB26-114 for vendor-provided technical details.

No verified exploit code is publicly available at the time of publication. Refer to Adobe's advisory for technical specifics.

Detection Methods for CVE-2026-48448

Indicators of Compromise

Anomalous SQL error messages or unusually long query strings in ACC application logs
HTTP requests to ACC endpoints containing SQL meta-characters such as ', --, UNION, or hex-encoded payloads
Unexpected outbound data transfers from ACC servers following suspicious inbound requests
Database query patterns retrieving system tables, memory functions, or file-read primitives

Detection Strategies

Deploy web application firewall (WAF) rules that flag SQL injection signatures targeting ACC URL paths
Enable verbose query logging on the ACC database and alert on queries referencing file-read functions or system catalogs
Correlate authentication-free HTTP requests with database anomalies to identify unauthenticated exploitation attempts
Baseline normal ACC request patterns and alert on deviations in parameter length, character sets, and request frequency

Monitoring Recommendations

Forward ACC web server, application, and database logs to a centralized SIEM for correlation and retention
Monitor for file system read operations initiated by the ACC service account outside expected directories
Track process and network telemetry on ACC hosts for signs of secondary access following suspected injection
Review outbound network flows from ACC infrastructure for exfiltration patterns to unknown destinations

How to Mitigate CVE-2026-48448

Immediate Actions Required

Apply the security update referenced in Adobe Security Advisory APSB26-114 as soon as feasible
Restrict network access to ACC management and application endpoints to trusted networks and VPN users
Review ACC and database logs for signs of prior exploitation, focusing on the period preceding patch deployment
Rotate credentials, API keys, and secrets accessible to the ACC service account if compromise is suspected

Patch Information

Adobe has released a security update for Adobe Campaign Classic addressing CVE-2026-48448. Consult Adobe Security Advisory APSB26-114 for the fixed versions and installation guidance specific to your deployment.

Workarounds

Place ACC behind a WAF with SQL injection rule sets tuned to the application's expected parameters
Limit database user privileges granted to the ACC service account, removing file-read and system-function permissions where possible
Segment ACC infrastructure so that compromise cannot pivot to adjacent systems holding sensitive data
Disable or restrict any ACC endpoints that are not required for business operations

bash

# Example WAF rule concept: block requests to ACC endpoints containing SQL meta-characters
# Adapt to your WAF syntax (ModSecurity example)
